Capture

 

 

 

 

 

1. In a CLEAN DRY environment unscrew the PT3 battery cap in a counter- clockwise motion.
2. Slide the cap and battery housing out of the PT3.
3. Remove the depleted battery out of its housing.
4. Insert a new battery into the battery housing oriented with the negative end touching the spring.
5. Align the groove along the battery housing with the guide bump inside the PT3 case and slide the battery housing back in.
6. Screw the battery cap back on to the PT3 in a clockwise direction. Do not over tighten.

II. Routine Maintenance

1. ALWAYS rinse the ORP sensor with clean water after each use.
2. ALWAYS replace the soaker cap with sponge filled with Sensor Storage
Solution to prevent the sensor from drying out after each use.
3. Cleaning the sensor: The Myron L Company recommends cleaning your sensor every two weeks, however this depends on application and frequency of use. Indications of a dirty sensor are slower and/or erroneous readings. Always recondition your sensor after cleaning.
To clean your sensor, select one of the following methods:
a. Basic Cleaning:
Using a solution made of dish soap mixed with water and a cotton swab, gently clean the inside of the sensor body and platinum electrode, rinse thoroughly with clean water, then recondition the sensor.
b. Moderate Cleaning:
Using a paste made of Comet® cleanser mixed with water and a cotton swab, gently clean the inside of the sensor body and platinum electrode, rinse thoroughly with clean water, then recondition the sensor. (If Comet® Cleanser is not available, use another mildly abrasive household cleanser).
c. Deep Cleaning:
Using ORP electrode cleaning paper and water, gently clean the platinum electrode, rinse thoroughly with clean water, then recondition the sensor.
4. Reconditioning the sensor: For greatest accuracy and speed of response, the Myron L Company recommends reconditioning the sensor after cleaning.
To recondition the sensor:
Rinse the sensor thoroughly with clean water, then allow it to soak in Storage Solution for a minimum of 1 hour (for best results allow the sensor to soak in Storage Solution overnight).
5. Do not drop, throw, or otherwise strike the PT3. This voids the warranty.
6. Do not store the PT3 in a location where the ambient temperatures exceed its specified Operating/Storage Temperature limits.

Calibration of the Ultrapen PT3 ORP Pen
The factory recommends calibrating twice a month, depending on usage. However, you should check the calibration whenever measurements are not as expected.
NOTE: If the measurement is NOT within calibration limits for any reason, “Error” will display. Check to make sure you are using a proper ORP calibration solution. If the solution is correct, clean the sensor as described im the manual under Routine Maintenance. (Reconditioning the sensor should not be necessary due to the high ionic strength of the calibration solutions.) Restart calibration.
NOTE: Small bubbles trapped in the sensor may give a false calibration. After calibration is completed, measure the ORP calibration solution again to verify correct calibration. Remember, in measurement mode you must manually correct for temperature variance from 25ºC. Example: At 25ºC, ORP2602OZ calibration solution will read 260mV; however, at 20.0ºC ORP2602OZ will read 265mV.
NOTE: If at any point during calibration, you do not submerge the sensor in solution
before the flashing slows, allow the PT3 to turn off and start over.

A. Calibration Preparation
1. Ensure the ORP sensor is clean and free of debris.
2. For maximum accuracy, pour a small amount of the calibration solution into a separate container to rinse the sensor in prior to calibration. If this is not possible, rinse the sensor in clean water prior to calibration.

B. Calibration
Use Myron L Company 80mV Quinhydrone, 260mV Quinhydrone, or 470mV Light’s ORP Calibration Solution.
1. Thoroughly rinse the PT3 by submerging the sensor in ORP calibration rinse solution and swirling it around.
2. Push and release the push button to turn the PT3 on.
3. Push and hold the push button. The display will alternate between “CAL”, “FAC CAL”, “ºCºF TEMP”, “ModE SEL” and “ESC”.
4. Release the button when “CAL” displays. The display will indicate “CAL” and
the LED will flash rapidly.
5. While the LED flashes rapidly, dip the PT3 in ORP calibration solution so that
the sensor is completely submerged.
6. While the LED flashes slowly, the display will indicate “ [value] CAL”; swirl the
PT3 around to remove bubbles, keeping the sensor submerged.
7. If the ORP calibration is successful, the display will indicate “CAL SAVEd”, then time out.
8. Verify calibration by retesting the calibration solution.

C. Factory Calibration
When ORP calibration solution is not available, the PT3 can be returned to factory default calibration using the FAC CAL function. This will erase any stored wet calibration.
NOTE: default factory calibration resets the electronics only and does NOT take the condition of the sensor into consideration.
To return your PT3 to factory calibration:
1. Push and release the push button.
2. Push and hold the push button. The display will alternate between “CAL”, “FAC CAL”, “ºCºF TEMP”, “ModE SEL” and “ESC”.
3. Release the button when “FAC CAL” displays. The display will alternate between “PUSHnHLD” and “FAC CAL”.
4. Push and hold the push button until “SAVEd FAC” displays indicating the PT3 has been reset to its factory calibration.

I.      Calibration

The factory recommends calibrating the Ultrapen PT2 pH tester twice a month, depending on usage. However, you should check the calibration whenever measurements are not as expected. 3-point Wet Calibration is most accurate and is recommended.

NOTE: If the measurement is NOT within calibration limits for any reason, “Error” will display. Check to make sure you are using a proper pH buffer solution. If the solution is correct, clean the glass bulb of the sensor with a cotton swab soaked in isopropyl alcohol. Restart calibration.

NOTE: Small bubbles trapped in the sensor may give a false calibration. After calibration is completed, measure the pH buffer solutions again to verify correct calibration.

NOTE: If at any point during calibration, you do not submerge the sensor in solution

before the flashing slows, allow the pen to power off and start over.

A.    Calibration Preparation

  1. For maximum accuracy, fill 2 clean containers with each pH buffer. Arrange them in such a way that you can clearly remember which is the rinse solution and which is the calibration buffer. If you don’t have enough buffer, you can use 1 container of each buffer for calibration and 1 container of clean water for all rinsing. Always rinse the pH sensor between buffer solutions.

2.   Ensure the pH sensor is clean and free of debris.

B.    3-Point Calibration

Use pH 7, 4 and 10 buffers for 3-point calibration.

1. Thoroughly rinse the pen by submerging the sensor in pH 7 buffer rinse solution and swirling it around.

2. Push and release the push button to turn the unit on.
3. Push and hold the push button. The display will alternate between “CAL”, “FAC CAL”, “ºCºF TEMP”, “ModE SEL” and “ESC”.
4. Release the button when “CAL” displays. The display will indicate “CAL” and the LED will flash rapidly. 
5. While the LED flashes rapidly, dip the pen in pH 7 buffer calibration solution so that the sensor is completely submerged. 
6. While the LED flashes slowly, the pH calibration point will display along with “CAL”. Swirl the pen around to remove bubbles, keeping the sensor submerged.
7.   If the pH 7 calibration is successful, the display will indicate “SAVED”, then “PUSHCONT” will be displayed.

8.   Push and release the push button to continue. The LED will begin flash rapidly.Repeat steps 5 through 8 with pH 4 and 10 buffer calibration solutions.After the 3rd calibration point is successfully saved, the display will indicate “SAVED” and power off.Verify calibration by retesting the calibration solution.

C.    2-Point Calibration

Use pH 7 and 4 or 10 buffers for 2-point calibration.

  1. Thoroughly rinse the pen by submerging the sensor in pH 7 buffer rinse solution and swirling it around.
  2. Push and release the push button to turn the unit on.
  3. Push and hold the push button. The display will alternate between “CAL”, “FAC CAL”, “ºCºF TEMP”, “ModE SEL” and “ESC”.
  4. Release the button when “CAL” displays. The display will indicate “CAL” and the LED will flash rapidly.
  5. While the LED flashes rapidly, dip the pen in pH 7 buffer calibration solution so that the sensor is completely submerged.
  6. While the LED flashes slowly, the pH calibration point will display along with “CAL”. Swirl the pen around to remove bubbles, keeping the sensor submerged.
  7. If the pH 7 calibration is successful, the display will indicate “SAVEd”, then “PUSHCONT” will be displayed.
  8. Push and release the push button to continue. The LED will begin flashimg rapidly.

Repeat steps 5 through 7 with pH 4 or 10 buffer calibration solution.

Leave the pen in the same buffer solution until the unit powers off. The offset will be applied to the remaining calibration point.
Verify calibration by retesting the calibration solution.

 

D.    1-Point Calibration

Use pH 7, 4 or 10 buffer for 1-point calibration.

  1. Thoroughly rinse the pen by submerging the sensor in pH buffer rinse solution and swirling it around.
  2. Push and release the push button to turn the unit on.
  3. Push and hold the push button. The display will alternate between “CAL”, “FAC CAL”, “ºCºF TEMP”, “ModE SEL” and “ESC”.
  4. Release the button when “CAL” displays. The display will indicate “CAL” and the LED will flash rapidly.
  5. While the LED flashes rapidly, dip the pen in pH buffer calibration solution so that the sensor is completely submerged.
  6. While the LED flashes slowly, the pH calibration point will display along with “CAL”; swirl the pen around to remove bubbles, keeping the sensor submerged.

If the pH calibration is successful, the display will indicate “SAVEd”, then “PUSHCONT” will be displayed. “PUSHCONT” will not display if you calibrated 4 or 10.

Leave the pen in the same buffer solution until the unit powers off. The offset will be applied to the remaining calibration points.

Verify calibration by retesting the calibration solution.

E.    Factory Calibration

When pH buffers are not available, the PT2 can be returned to factory default calibration using the FAC CAL function. This will erase any stored wet calibration. NOTE: default factory calibration resets the electronics only and does NOT take the condition of the sensor into consideration.

To  return your unit to factory calibration:

  1. Push and release the push button.
  2. Push and hold the push button. The display will alternate between “CAL”, “FAC CAL”, “ºCºF TEMP”, “ModE SEL” and “ESC”.

*Note: This procedure applies to the Ultrameter, PoolPro, TechPro, and D-6 Dialysate meter.

IMPORTANT: Always “zero” your Ultrameter II with a pH 7 buffer solution

before adjusting the gain with acid or base buffers, i.e., 4 and/or 10, etc.

a. pH Zero Calibration (6PFCE)

1. Rinse sensor well and cell cup 3 times with 7 buffer solution.

2. Refill both sensor well and cell cup with 7 buffer solution.

3. Press

pH

 

 

 

 

to verify the pH calibration. If the display shows 7.00, skip the pH

Zero Calibration and proceed to pH Gain Calibration.

4. Press

CAL key

 

 

 

 

 

to enter calibration mode. “CAL”, “BUFFER” and “7” will appear on the display.

display

 

 

 

 

 

 

 

Displayed value will be the uncalibrated sensor.

NOTES: If a wrong buffer is added (outside of 6-8 pH),“7” and “BUFFER

will flash, and the Ultrameter II will not adjust.

The uncalibrated pH value displayed in step 4 will assist in determining

the accuracy of the pH sensor. If the pH reading is above 8 with pH 7

buffer solution, the sensor well needs additional rinsing or the pH sensor

is defective and needs to be replaced.

5. Press

Up

 

 

 

 

or

Down

 

 

 

 

until the display reads 7.00.

NOTE: Attempted calibration of >1 pH point from factory calibration will

cause “FAC” to appear. This indicates the need for sensor replacement

or fresh buffer solution. The “FAC” internal electronic calibration is not intended to

replace calibration with pH buffers. It assumes an ideal pH sensor. Each “FAC”

indicates a factory setting for that calibration step (i.e., 7, acid, base).

You may press

CAL key

 

 

 

 

 

to accept the preset factory value, or you may

reduce your variation from factory setting by pressing

Up

 

 

 

 

or

Down

 

 

 

 

6. Press to accept the new value. The pH Zero Calibration

is now complete. You may continue with pH Gain Calibration or

exit by pressing any measurement key.

b. pH Gain Calibration (6PFCE)

IMPORTANT: Always calibrate or verify your Ultrameter II with a pH 7

buffer solution before adjusting the gain with acid or base buffers, i.e.,

4 and/or 10, etc. Either acid or base solution can be used for the 2nd

point “Gain” calibration and then the opposite for the 3rd point. The

display will verify that a buffer is in the sensor well by displaying either

Acd” or “bAS”.

1. The pH calibration mode is initiated by either completion of the

pH Zero Calibration, or verifying 7 buffer and pressing the

CAL key

 

 

 

 

 

key twice while in pH measurement mode.

2. At this point the “CAL”, “BUFFER” and “Acd” or “bAS

will be displayed (see Figures 7 and 8).

Capture

 

NOTE: If the “Acd” and “bAS” indicators are blinking, it indicates

an error and needs either an acid or base solution present in the sensor

well.

3. Rinse sensor well 3 times with acid or base buffer solution.

4. Refill sensor well again with same buffer solution.

5. Press

Up

 

 

 

 

or

Down

 

 

 

 

until the display agrees with the buffer value.

6. Press

CAL key

 

 

 

 

 

to accept the 2nd point of calibration. Now the

display indicates the next type of buffer to be used.

Single point Gain Calibration is complete. You may continue for the 3rd

point of Calibration (2nd Gain) or exit by pressing any measurement key.

Exiting causes the value accepted for the buffer to be used for both acid

and base measurements.

To continue with 3rd point calibration, use basic buffer if acidic buffer

was used in the 2nd point, or vice-versa. Again, match the display to the

known buffer value as in step 2 and continue with the following steps:

7. Repeat steps 3 through 6 using opposite buffer solution.

8. Press

CAL key

 

 

 

 

 

to accept 3rd point of calibration, which completes the Calibration procedure.

Fill sensor well with Sensor Storage Solution and replace protective cap.

My 750 Series II Monitor or Monitor/Controller display shows a 1, then a space, then a decimal point. What does this mean?
This is an over-range condition that can be fixed by performing an Electronic calibration of the circuit board. Please see directions in the Operations Manual or follow this brief review of Electronic Calibration. Hook up a Multi-Meter to the R+ and R- leads located at the top of the circuit board, switch the Multi-Meter to DC volts, push the Full Scale Push to Test button and read the DC voltage on the Multi-Meter. While pushing the Full Scale Push to Test button, adjust the CAL screw on the circuit board until the Multi-Meter reads 9.95-10.00 VDC. The display on the Myron L Monitor or Monitor/Controller should now read Full Scale.

How do I pick the correct range module for my Monitor or Monitor/Controller?
You must pick a range module that covers your 2/3 of your operating range. If you pick a range module that is too broad, then your accuracy will suffer or it will not show a number on the display. For example, if your operating range is 100-150 microsiemens, a range module of 0-200 microsiemens (-115) would be a good choice. A range module of 0-5,000 microsiemens (-123) would not be a good choice for this application.

Why does my displayed number fluctuate?
There is air or air bubbles around the sensor or the sensor is not properly installed. Tap on the sensor body to dislodge air bubbles or loosen securing nut to release trapped air. The sensor tip must be in the flow of water.

My device connected to the dry contact relay does not work and has no power. What do I do?
The Myron L dry contact relay does not draw power from the circuit board. You must supply the power to the relay to power your device.

Why is the display number on the Monitor or Monitor/Controller negative?
This is the offset that is being display and is caused when the sensor is not hooked up or is hooked up and sitting in air.

Why is the displayed number on the Monitor or Monitor/Controller half the reading than it should be?
This is caused when the 115/230 VAC switch is set to 230VAC when in fact it should be switched to 115 VAC.

Does the Aquaswitch I require any other device to help it switch banks?

Yes, the AquaSwitch I requires a Monitor/Controller in order to switch banks.

What is the recommended method to mount a Conductivity or Resistivity sensor?
The optimal method to mount the sensor is in the end of a tee with the water flowing directly into the tip of the sensor and flowing up and away at a 90 degree angle. Please see the 750 Series II Operations Manual for complete instructions.

I want to use my Monitor or Monitor/Controller for another application but the water quality is a totally different range. Can my existing unit be changed?
Our 750 Series II Conductivity/TDS and Resistivity Monitors and Monitor/Controllers can be “Re-Ranged” with a new range module to meet you changing needs. Simply un-plug the old range module and plug in the new range module into the circuit board. Refer to page 8 of the Operations Manual to see the Range Selection guide and to see if any minor modifications are necessary.

How can I tell what the model number of my Monitor or Monitor/Controller is?
The module number is circled on the transformer and printed on the back of the case.

Please note:  These procedures apply to Ultrameters, Pool Pros, Tech Pros, and D-4 and D-6 dialysate meters.

Measuring Conductivity & TDS

1. Rinse cell cup 3 times with sample to be measured. (This conditions

the temperature compensation network and prepares the cell.)

2. Refill cell cup with sample.

3. Press COND or TDS.

4. Take reading. A display of [- – – -] indicates an over range condition.

Measuring Resistivity

Resistivity is for low conductivity solutions. In a cell cup the value may drift from trace contaminants or absorption from atmospheric gasses, so measuring a flowing sample is recommended.

1. Ensure pH protective cap is secure to avoid contamination.

2. Hold instrument at 30° angle (cup sloping downward).

3. Let sample flow continuously into conductivity cell with no aeration.

4. Press RES key; use best reading.

NOTE: If reading is lower than 10 kilohms display will be dashes: [ – – – – ]. Use Conductivity.

 IV. AFTER USING THE ULTRAMETER II

Maintenance of the Conductivity Cell

Rinse out the cell cup with clean water. Do not scrub the cell. For oily films, squirt in a foaming non-abrasive cleaner and rinse. Even if a very active chemical discolors the electrodes, this does not affect the accuracy; leave it alone.
