MAINTENANCE Ultrapen PT3 ORP Pen
I. Battery Replacement
The PT3 display has a battery indicator that depicts the life remaining in the battery. When the indicator icon is at 3 bars, the battery is full. When the indicator icon falls to 1 bar, replace the battery with an N type battery.

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.

The Ultrapen PT1 is designed to be very reliable and requires only infrequent calibration. The factory recommends calibrating each measurement mode you use once monthly. However, you should check the calibration whenever measurements are not as expected. The PT1 is programmed for 2 calibration options: Wet Calibration or Factory Calibration. Wet calibration is most accurate. But if a high quality standard KCl-1800 µS or 442-3000 ppm solution is not available, the PT1 can be returned to factory settings.

A. Wet Calibration
Use calibration solution specified for measurement mode: Use KCL- 1800 for Cond KCl; Use 442-3000 for tdS 442, SALt 442, tdS NaCl, and SALt NaCl. See Specifications table for 442 solution ppm NaCl equivalent value. Calibrating TDS simultaneously calibrates SALT for the same value and vice versa.
1. Pour calibration solution into a clean container.
2. Rinse the pen 3 times by submerging the cell in fresh calibration solution and swirling it around.
3. Remove pen from solution, then fill the container one more time.
4. Press and release the push button. The LCD will briefly display the firmware version then the current measurement mode. Ensure the PT1 is in the correct solution mode.
5. Immediately push and hold the push button. The display will scroll through “CAL”, “SOL SEL”, “FAC CAL”, “ºCºF TEMP”, and “ESC”. Release the button when “CAL” displays.
6. Grasp the pen by its case with your fingers positioned between the
display and the pen cap to avoid sample contamination.
7. While the LED flashes rapidly, dip the pen in calibration solution so that the cell is completely submerged. If you do not submerge the cell in solution before the fl slows, allow the pen to power off and start over.
8. While the LED flashes slowly, swirl the pen around to remove bubbles, keeping the cell submerged. Keep pen at least 1 inch (2½ cm) away from sides/bottom of container.
9. When the LED light stays on solid, remove the pen from the solution. “CAL SAVED” will display indicating a successful calibration.
Note: If an incorrect solution is used or the measurement is NOT within calibration limits for any other reason, “Error” displays alternately with “CLEAn CEL/CHEC SOL”. Check to make sure you are using the correct calibration solution. If the solution is correct, clean the cell by submerging the cell in a 1:1 solution of Lime-A-Way® and water for 5 minutes. Rinse the cell and start over.
10. Small bubbles trapped in the cell can give a false calibration. Measure the calibration solution again to verify correct calibration. If the reading is not within ±1% of the calibration solution value, repeat calibration.

B. Factory Calibration
If you do not have the proper calibration solution or wish to restore the pen to its original factory settings for any other reason, use the FAC CAL function to calibrate the PT1.
1. Press and release the push button. The LCD will briefly display the firmware version then the current measurement mode.
2. Immediately push and hold the push button. The display will scroll through “CAL”, “SOL SEL”, “FAC CAL”, “ºCºF TEMP”, and “ESC”. Release the button when “FAC CAL” displays.
3. While the display scrolls through “PUSHnHLD” and “FAC CAL”, push and hold the push button until the display scrolls through “SAVEd” and “FAC CAL”, indicating the pen has been reset to its factory calibration.
4. Allow the pen to time out to turn power off.

III. Normal Operation

Before you take a reading, make sure the pen is clean, calibrated and in the appropriate measurement mode. The sample solution must also be within the specified measurement range. Keep all foreign material away from the sample to avoid contamination.

Note: If you cannot dip the pen in the sample solution, pour the sample into a clean container. If you don’t have a sample container and need to test a vertical stream of solution, use the scoop.

The following table explains what the LED Indicator Light signals mean and gives the duration of each signal.

LED Indicator Light Signal Meaning duration

Rapid Flashing Dip pen in solution 6 sec

Slow Flashing Measurement in process 10-20 sec

Solid Light Note measurement value 6 sec

CAUTION: To measure solution at the extremes of the specified temperature range, allow the pen to equilibrate by submerging the cell in the sample solution for 1 minute prior to taking a measurement.

1. Rinse the pen 3 times by submerging the cell in fresh sample solution and swirling it around.

2. Remove pen from solution, then press and release the push button. Firmware version will be displayed, then current measurement mode.

3. Grasp the pen by its case with your fingers positioned between the display and the pen cap to avoid sample contamination.

4. While the LED flashes rapidly, dip the pen in fresh sample solution so that the cell is completely submerged. If you do not submerge the cell in solution before the flashing slows, allow the pen to power off and retake the reading.

5. While the LED flashes slowly, swirl the pen around to remove bubbles, keeping the cell submerged. Keep the pen at least 1 inch (2½ cm) away from sides/bottom of container, if applicable.

6. When the LED turns on solid, remove the pen from solution. The display will alternate between the measurement and temperature readings. Note the readings for your records.
