Operating menus for the measured variables pH and ORP
During calibration, the DULCOMETER
'0' . Exception to this: a basic load or a manual control variable has been set. This
remains active. The mA standard signal output is frozen.
When calibration/testing has been completed successfully, all of the error checks relating
to the reading are restarted. The DULCOMETER
determined data for zero point and slope when the calibration is successful.
