to the value of DPD1 reading
test and then confirm by Enter.
POTENTIOSTATIC CHLORINE PROBE CALIBRATION
Attention, it will be necessary to do a comparative free chlorine test (for example a DPD1 photometric test)
ZERO CALIBRATION is executed at factory and then go directly to gain calibration.
V-MS is been projected so that the electrical zero probe calibration is equal to electrochemical zero calibration.
So if it's really necessary to calibrate the zero of the probe, read the following instructions:
Switch off V-MS and open the connection box.
Disconnect the chlorine probe input connection from the chlorine board (refer to the next figure).
Switch on V-MS and wait until the display reaches a stable reading (any value).
