If an invalid code is
entered, the device

Welcome (3 sec) Device in HOLD mode,
Sensoface inactive.
Modify the zero point
until the lower display reads
0 μS.
If required, change the
sign of the zero point.
When there has not been
an entry for 6 sec, the
lower display alternately
shows the zero-corrected
conductivity value and
the temperature value.
Press enter to confi rm the
zero point.
Press
enter to exit the HOLD
mode.
After 20 sec (for measured
value stabilization) the
device returns to measur-
ing mode.
A zero calibration is required when low conductivity values are to be measured.
Before you start calibration, remove the sensor from the process, clean it and dry it
up.
