Caution!
When calibrating the following sensor measuring modules in the
pressurised version:
pH value
ORP potential
Conductivity
Fluoride
Membrane sensors for free chlorine, chlorine dioxide, ozone
and Total chlorine
You must also perform the following:
Before calibration:
Close the ball valves on the inlet and outlet.
Depressurise the unit. To this purpose, briefly open and close
the knurled nut on the drain.
After calibration:
Open the inlet and outlet.
Caution!
The electrode fingers or membranes on the sensors are extremely
sensitive! Do not touch, soil or damage.
Caution!
Note the safety data sheets for buffer solutions.
Please note
To prevent the output of non-permissible control signals during
calibration, the "Hold function" in the system menu (display 1.7.1
“System - Menu 1.7" on page 141) should be set to "On" (mA-
outputs and controller outputs then remain constant during
calibration). 2.1.5 “Calibration - Menu 2.1" on page 147).
To determine how often you must calibrate, refer to 7.1
“Maintenance Schedules" on page 203.
