2.6. Calibration
Calibration is for adjusting the displayed value of a probes reading to match your tester or known solution.
CALIBRATION - For adjusting the actual reading
values of the available analog probe inputs, such as
conductivity, pH, ORP or temperature.
2.6.a. Conductivity Calibration
CALIBRATE - With a clean probe on-line seeing the
handheld tester) value.
RESET ZERO - With the probe out of solution and dry,
enter a new zero point. Note: Probe must be dry!
NOTE: In the calibration pop-up window, the raw analog-to-digital (A/D) value will be displayed. A new
calibration value should only be entered when the probe is sensing a stable A/D value. If the system is a
boiler the associated relay can be forced on in the pop-up to allow for a fresh hot sample. Boiler probes should
have fresh hot water blown past them for a minimum of 2 minutes before calibrating. The A/D reading has
a range of 0 to 32,767. If it is at one end of the range or the other when trying to calibrate, something
is wrong with the probe or wire run.
2.6.b. pH and ORP Calibration
1 POINT - With a clean probe on-line seeing the
handheld tester) value.
2 POINT - Enter a known Low value with a clean probe
Notes:
Point calibration and given at least 30 seconds in solution
