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.

CAUTION: To measure solution at the extremes of the specified temperature or ORP range, or when changing between solutions that have extreme differences in ORP values, or from high to low ionic strength: Rinse the sensor thoroughly with clean water then allow it to soak in a sample of the solution to be tested for a minimum of 1 minute.
(In some applications you may want to allow the sensor to soak in solution for an hour or more.)
NOTE: If you cannot dip the sensor in the sample solution, pour the sample into a clean container. If you don’t have a container or need to test a vertical stream of solution, use the scoop to hold sample solution.

1. Rinse the PT3. If measuring from a container, submerge the sensor and swirl it around in FRESH sample solution 3 times. Alternatively, 30 seconds under a stream or swirling in a body of water is sufficient to prepare the sensor for measurement.
2. Remove PT3 from solution. (Fill the container one more time with FRESH sample solution, if applicable.) Then push and release the push button.
3. Grasp the PT3 by its case with your fingers positioned between the display

* 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.

Ultrapen PT2 Calibration
We recommend calibrating 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. You can find the buffer solutions here: http://www.myronlmeters.com/pH-Buffer-Calibration-Solutions-s/82.htm
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 flashing rapidly.
9. Repeat steps 5 through 8 with pH 4 and 10 buffer calibration solutions.
10. After the 3rd calibration point is successfully saved, the display will indicate
“SAVEd” and power off.
11. 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 flashing rapidly.
9. Repeat steps 5 through 7 with pH 4 or 10 buffer calibration solution.
10. Leave the pen in the same buffer solution until the unit powers off. The offset will be applied to the remaining calibration point.
11. 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.
7. 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.
8. Leave the pen in the same buffer solution until the unit powers off. The offset will be applied to the remaining calibration points.
9. 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”.
3. Release the button when “FAC CAL” displays. The display will alternate between “PUSHnHLD” and “FAC CAL”.
4. Push and hold the push button. “SAVEd FAC” displays indicating the pen has been reset to its factory calibration.
