ULTRAPEN™ PT3 – Quick Start Guide
ORP and Temperature Pen
PT3QSI 07-21
III. CALIBRATION:
Myron L
®
Company recommends performing a calibration of the PT3 twice a month or any time measurements are not as
expected.
•
The PT3 has embedded automatic temperature compensation in calibration mode (from 15ºC to 30ºC) for three calibration solutions (80 mV and
260 mV Quinhydrone as well as 470 mV Light’s Solution).
For more information, visit www.myronl.com/pt3.htm.
•
Small bubbles trapped in the sensor may give a false calibration.
1.
Rinse the PT3 sensor in ORP solution.
•
The PT3 will automatically identify which ORP standard solution you are using.
2.
Press and release the push button to turn the PT3 ON.
3.
Push and Hold the button down.
4.
Release the button when “CAL” is displayed.
5.
Grasp the pen near the battery cap to avoid sample contamination.
6.
While the LED flashes rapidly, dip the pen in fresh sample solution so that the sensor is completely submerged.
•
If you do not submerge the sensor in solution before the flashing slows, allow the pen to power OFF and retake the reading.
7.
While the LED flashes slowly, swirl the pen around to remove bubbles, keeping the sensor submerged.
•
If possible, keep the pen at least 1 inch (2½ cm) away from sides/bottom of container.
8.
When the LED turns ON solid, remove the pen from solution.
•
The display will read “CAL SAVED” and the PT3 will turn OFF.
•
If “Error” appears on the display, check to make sure you are using a proper, Myron L
®
Company, ORP Standard Solution.
•
If the solution is correct, clean the sensor, as described in the full PT3 Operation Manual downloadable from the Myron L
®
Company website.
FACTORY CALIBRATION
:
Factory Calibration (FAC CAL) resets the PT3 to its factory settings. For instructions on how to perform a FAC CAL

Company website.
MAINTENANCE
I. BATTERY REPLACEMENT:
1.
In a clean, dry place unscrew the battery cap in a counter-clockwise motion.
2.
Slide the cap and battery housing out of the pen.
3.
Remove the depleted battery from its housing.
4. I
nsert 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
pen case and slide the battery housing in.
6.
Screw the pen cap back on in a clockwise direction. Do not over tighten.
II. ROUTINE MAINTENANCE
1.
After each use,
ALWAYS
rinse the sensor with clean water (preferably DI,
RO, or purified water), then carefully blot the sensor with a soft, clean cloth
to remove any water drops.
2.
ALWAYS
replace the Soaker Cap (filled half way with Myron L
®
Company
Storage Solution) on the sensor after each use.
DO NOT
push the cap past the Cap Stop.
3.
Do not drop, throw or otherwise strike the PT3. This voids the warranty.
4.
Do not store the PT3 in a location where the ambient temperatures exceed its specified Operating/Storage Temperature limits.
II. SENSOR CLEANING AND REPLACEMENT:
