For a complete set of operating instructions, maintenance procedures, calibration procedures, and the FACTORY CAL reset procedure, download the
full PT2 Operation Manual from www.myronl.com.
1. Press and release Push Button to turn the PT2 ON.
2. LED flashes rapidly: Dip pen in sample solution so sensor is totally submerged.
3. LED flashes slowly: Swirl pen in sample, keeping sensor submerged. Avoid contact with sides/bottom of container.
LIVE Mode: Display will alternate between live pH and temperature readings. Note readings for your records.
HOLD Mode: LED turns Solid ON when Measurement is complete then pen turns OFF.
NOTE: After turning the PT2 ON, press and hold the push button to enter either the calibration or configuration mode.
1. PUSH BUTTON – Press to turn PT2 ON and select mode
settings.
2. BATTERY CAP – Unscrew to access battery for replacement.
3. BATTERY INDICATOR – Indicates life remaining in battery.
4. DISPLAY – Displays measurements and menu options.
5. LED INDICATOR LIGHT – Tells the user when to dip & swirl
PT2 during measurements and calibration.
6. pH SENSOR – Measures test sample's Hydrogen ion
concentration and temperature.
7. PROTECTIVE/HYDRATION CAP – Contains pH Sensor
Storage Solution to maintain sensor hydration. To remove,
wiggle the cap back and forth while pulling it off using caution
not to spill the Storage Solution. To replace, fill the
protective/hydration cap half full with storage solution. Wiggle
the cap back and forth while pushing back on using caution as
excess Storage Solution may squirt out. Do NOT push the cap
beyond the Cap Stop as sensor damage may occur.
NOTE: The formation of KCl crystals around the protective/hydration cap is normal. These crystals do not affect the sensor life, performance, or
accuracy provided they are rinsed off with water prior to a test.
8. CAP STOP – DO NOT push the protective/hydration cap beyond the Cap Stop as sensor damage may occur.
9. SCOOP – Used to hold sample solution when dipping is not possible. To install, push the scoop onto the sensor while shifting side-to-side. To
remove, pull the scoop off while shifting side-to-side. Verify the pH sensor remained fully inserted into the PT2. If not, reinstall per pH Sensor
Replacement instructions (see Maintenance section of this guide). To use, hold the scoop directly under a vertical stream during measurement,
avoiding bubbles.
Temperature Units: °C (Temp. value alternates on Display with pH value)
NOTE: For instructions on changing the temperature units to °F or switching the PT2 to LIVE measurement mode download the full PT2 Operation

MEASUREMENT SETUP

: Before you take a reading, make sure the pen is clean, calibrated, and in the desired measurement mode. The sample
solution must also be within the specified measurement range.
NOTE: Selecting "ESC" from any menu immediately turns the PT2 OFF without saving changes.
CAUTION: To measure solution at the extremes of the specified temperature range, allow the pen to equilibrate by submerging the sensor in the sample
solution for 1 minute prior to taking a measurement.

MEASUREMENT

:
1. Rinse the sensor by swirling it in fresh sample solution 3 times.
2. Push and release the push button to turn the PT2 ON.
3. Grasp the pen near the battery cap to avoid sample contamination.
4. Swirl the PT2 in fresh solution while measurement is taking place. If you do not submerge the sensor in solution before the flashing slows, allow the
pen to power OFF and retake the reading.
5. The following table explains how to follow LED prompts during measurement and shows the duration of each prompt:
