The instructions in this paragraph apply to eTwin Chlorine - pH
models. The Chlorine probe must be connected to the pump through
the specific cable: having connected BNC, the remaining two cables
must be inserted in the cable gland and connected to the "inputs"
terminal board.

PROBES CALIBRATION MENU
To allow the device to correctly detect the parameters of the water to be checked, the probes connected to it must be calibrated.
Either electrodes made of glass or plastic can be used. The instructions for calibrating the probe apply to all eTwin device models and
versions
During the calibration, the pH, Rx and PPM values displayed on the left of the screen represent the real time values of
the reading of the probe, while those displayed on the right of the screen are the values of the BUFFER solutions used to
calibrate the different points.
Attention: if calibration is not carried out correctly or the readings are not even made on the instrument, they could have
serious errors with non-negligible consequences on the health and safety of the users.
To access the CALIBRATION menu, press

for about 5 seconds.
