Display Action Remark
At the end of the adjustment
procedure the zero offset [mV]
of the electrode is displayed
(based on 25 °C).
Press enter to proceed.
This is not the final
calibration value of
the electrode! Zero
point and slope must
be determined using
a complete 2-point
calibration (cal 1100)
(see following pages).
Confirmation prompt.
Display of pH value (alternately
with Hold) and temperature,
“enter” blinks, Sensoface is
active.
Place electrode in process.
Press enter to end zero
calibration.
After end of calibra-
tion, the outputs
remain in Hold
mode for approx.
20 sec.
Note for zero adjustment
After having adjusted the nominal zero point, be sure to calibrate
the electrode following one of the procedures as described on
the next pages:
• Automatic calibration with Calimatic
• Manual calibration
• Data entry of premeasured electrodes
