A.1.6 Calibration Methodology
1. You must have an accurate reading of the system water to properly calibrate the monitor.
•
A properly calibrated handheld temperature, conductivity, or pH meter may be acceptable for
completing calibrations
•
NOTE: If at any time you believe that the pH, conductivity, or temperature calibrations have
been improperly performed, you may reinitialize the calibrations and restore them to their
default values.
2. Calibrate the temperature first.

•
Press PRO on the keypad, select ZERO
