Sensocheck, Sensoface sensor monitoring

Sensocheck continuously monitors the sensor and leads.
Sensocheck can be switched off (Configuration, Pg 51).
Note: When measuring with DURAFET electrodes,

GainCheck device self test

A display test is carried out, the software version is displayed
and the memory and measured value transfer are checked.
Start GainCheck device self-test:

Automatic device self-test

The automatic device self-test checks the memory and meas-
ured-value transfer. It runs automatically in the background at
fixed intervals.
APT4000PH
Sensoface provides information on the electrode condi-
tion. The asymmetry potential (zero), slope and
response time during calibration are evaluated. The
three Sensoface indicators provide the user with infor-
mation about wear and required maintenance of the
sensor.
Sensocheck is not active.
