7.1 Conductivity Calibration
The HC1000 is capable of using conductivity electrodes with different cell
constants.
Before use, ensure that the correct cell constant is selected (0.1, 1 or 10) in
the setup menu
. If the current option is “USER”, the automatic calibration
function will be disabled (Refer to Setup Menu section).
In the automatic calibration mode, the meter allows up to a 5 point calibration.
To ensure higher accuracy, at least a 3 point calibration is recommended.
Alternatively, it is advised to select a standard value close to the sample
value under measurement.
The meter will automatically detect common conductivity standard solutions
and prompt the user to calibrate the meter.
When the calibration is completed, all new calibration values will
automatically override existing data.
The following table shows acceptable conductivity range of calibration
solution for each measuring range.
