QUICK REFERENCE INSTRUCTIONS
1.
Press and release Push Button to turn ON the PT3.
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 PT3 ON, press and hold the push button to enter either the calibration or configuration mode.
FEATURES
1. PUSH BUTTON
– Press to turn PT3 ON and select mode settings.
2. BATTERY CAP
– Unscrew to access battery for replacement.
3. BATTERY INDICATOR –
Shows battery charge level.
4. DISPLAY -
Displays measurements and menu options.
5. LED INDICATOR LIGHT
- Tells the user when to dip & swirl PT3
during measurements and calibration.
6.
ORP SENSOR
– Contains ORP and Temperature sensor apparatus.
7. PLATINUM ELECTRODE
– Measures
oxidation-reduction potential
(ORP) or redox of solution.
8.
THERMISTOR
– Measures test sample’s temperature.
9. SOAKER CAP
–
Contains a sponge soaked in Sensor Storage
Solution to maintain sensor hydration.
•
To remove, twist the cap and pull off. Do not spill the Storage
Solution.
•
To store the PT3 between uses, fill the cap until sponge is covered. Twist the cap while pushing it onto the ORP Sensor. Do not over fill the cap
or excess solution may squirt out.
NOTE
: The formation of KCl crystals around the soaker cap is normal.
•
These crystals do not affect the sensor life, performance, or accuracy.
•
ALWAYS
rinse them off with clean water prior to a performing a test.
10.
CAP STOP
–
DO NOT
push the Soaker Cap beyond the Cap Stop as sensor damage could occur.
11.
ORP ELECTRODE CLEANING PAPER — For deep cleaning the platinum electrode.
12. 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 sensor remained fully inserted into the PT3. If not, download the full PT3 Operation
Manual from the Myron L
®
Company website for instructions on reinstalling the Sensor. To use, hold the scoop directly under a vertical stream
during measurement, avoiding bubbles.

OPERATING INSTRUCTIONS
I.
MEASUREMENT SETUP:
The following steps should be taken prior to performing a measurement with your PT3:
1.
Make sure the pen is clean
2.
Myron L
®
Company
recommends that you calibrate the PT3 before taking measurements (See section III).
II.
NORMAL OPERATION:
CAUTION
:
:
To measure solutions 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.
NOTE
: When testing a vertical stream of sample, use the scoop. Recalibrate the pen using the scoop to for best results.
1.
Rinse the sensor by swirling it in a container of fresh sample solution or for approximately 30 seconds.
•
If using the scoop, hold the scoop under the sample stream for approximately 30 seconds
2.
Remove the PT3 from rinse and pat it dry with a clean cloth or tissue.
3.
Refill the sample container with fresh test sample.
4.
Push and release the push button to turn the PT3 ON.
5.
Grasp the pen near the battery cap to avoid sample contamination.
6.
Swirl the PT3 in the sample 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.
•
If possible, keep the pen at least 1 inch (2½ cm) away from sides/bottom of container, if applicable.
