OFFSET CALIBRATION
Zero Calibration is executed at factory. It is not necessary and it is not recommended!
The pump 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:
1) Disconnect the chlorine probe input from
the pump and short-circuit the
pins 2
and
3
on connector C (eg using a screwdriver) on
the pump.
2) Wait until the display reaches a stable
reading (any value).
3) Push
ENTER/MENU
for 3 seconds and
with ▼▲ buttons scroll the cursor on
Calibration
and push
ENTER.
The cursor is
on
Offset
and so push
ENTER
. The display
shows the reading. Push
ENTER
and then
modify (if necessary) the shown value at
0ppm with ▼▲ buttons and then confirm with
ENTER.
