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.

* Temperature compensation in calibration mode: Temperature affects the reaction potentials for all chemicals differently. True ORP is the direct measurement of electron activity during an oxidation-reduction reaction, regardless of temperature. However, for maximum accuracy and ease of calibration, the Myron L Company has developed three calibration solutions with known dissolved species. We derived the temperature compensation (from 15ºC to 30ºC) for those solutions, and embedded automatic temperature compensation into the calibration function of your PT3. Note: To verify calibration while in measurement mode, you must manually correct for any variation in temperature. Example: @25ºC, ORP2602OZ calibration solution will read 260mV, however @ 20.0ºC ORP2602OZ will read 265mV.

Calibrating the Ultrapen PT2 pH Tester: MyronLMeters.com

Posted by 3 Apr, 2014

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”.

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.

Ultrapen PT1 Conductivity, TDS and Salinity Calibration: Myron L Meters

Posted by 3 Apr, 2014

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.

4. “SAVED” displays indicating the measurement mode is saved in memory. Allow the pen to time out to turn power off.

II. Temperature Unit Selection

The PT1 allows you to select the type of units used for temperature measurements. The following table lists preference options with their corresponding units.

Mode Unit Preference

C Degrees Celsius

F Degrees Fahrenheit

esc This is the escape function. Selecting escape exits temperature unit selection without saving changes and turns the PT1 off.

To set the preference:
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 “ºCºF TEMP” displays.
3. While the display scrolls through “PUSHnHLD” and “ºCºF TEMP”, push and hold the push button. The display will scroll through “C”, “F” and “ESC”. Release when the desired unit option displays.
4. “SAVED” displays indicating the unit preference is saved in memory.
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.

Ultrapen PT1 Conductivity, TDS, Salinity Pen Features: MyronLMeters.com

Posted by 3 Apr, 2014

The ULTRAPEN™ PT1 Conductivity/ TDS/Salinity Pen is designed to be extremely accurate, fast and simple to use in diverse water quality applications. Advanced features include the ability to select from 3 different solution types that model the characteristics of the most commonly encountered types of water; proprietary temperature compensation and TDS conversion algorithms; highly stable microprocessor-based circuitry; user-intuitive design; and waterproof housing. A true one-handed instrument, the PT1 is easy to calibrate and easy to use. To take a measurement, you simply press a button then dip the pen in solution. Results display in seconds.

Features
1. Push Button — turns instrument on; selects mode and unit preferences.
2. Pen Cap — provides access to battery for replacement.
3. Clip — holds pen to shirt pocket for secure storage.
4. Battery Indicator — indicates charge left in battery.
5. display — displays measurements, mode options and battery indicator.
6. LED Indicator Light — indicates when to dip instrument in solution, when measurement is in progress, and when to remove instrument from solution.
7. electrodes — measure electric current of solution.
8. Cell — contains flux field in defined area for accurate current
measurement.
9. scoop — contains sample solution for measurement when sampling from a vertical stream. To use, slide the open end of the scoop over the bottom of the pen until the neck of the scoop is flush with the top of the cell. Hold pen with scoop end under stream. Rinse and fill with sample solution 3 times. Fill with solution again, then take measurement. We recommend you recalibrate the pen using the scoop to retain accuracy of ±1%.
