Temperature Calibration Steps
1. Place the probe and a reference thermometer (with 0.1 ° resolution) into a stirred container of water.
2. Observe the temperature on display until it stops changing. This may take several minutes.
3. Calculate the Temp.Offset (i.e. reference thermometer temperature minus probe temperature).
4. Press
m from the Measure mode.
5. Select Setup from Channel parameter.
6. With Probe Settings selected, press Setup.
7. At prompt, enter the passcode.
8. Press the
ud keys to scroll to Temp.Offset, then Set.
9. At prompt, press YES, to place unit in HOLD.
10. Adjust blinking digits to the Temp.Offset calculated at step 3. Press CFM.
11. Press
b to exit, and at prompt to confirm the change.
Temp. Source and Manual Temperature Value
The probe provides an accurate temperature used for temperature compensation and measurement.
In the event the temperature sensor inside the probe experiences a failure or other issue, the control process
may continue using a manual temperature which should be set close to the process’s temperature. A “!!” is
displayed. We suggest to order a replacement probe as soon as this occurs.
