5.7 Process Variable pH
Note: Function check (HOLD) is active.
Note: After changing the process variable or measuring mode, Stratos Multi retains its settings but
needs to be reconfigured.

Sensor Data, p. 66
Sensoface Enable/disable display of Sensoface messages and icons.
Sensor Monitoring Details Option to enter individual limits for monitoring slope and
zero point.
Enable/disable Sensocheck sensor monitoring. Set whether
Sensocheck should generate failure or maintenance required
messages.
Option to enter individual values before a message is trig-
gered for response time, sensor wear, sensor operating time
and SIP counter; also CIP counter with pH/ORP sensors; also
operating point and leakage current with ISFET sensors.
