Adaptive cal timer
(ACT)
By issuing a Sensoface message, the adaptive
calibration timer reminds you to calibrate the
sensor. The ACT interval is either read auto-
matically from the sensor settings or can be
specified manually.
Stressing influences (temperature, measure-
ment in extreme ranges) shorten the timer
interval.
Adaptive mainte-
nance timer (TTM)
By issuing a Sensoface message, the adaptive
maintenance timer reminds you to service
the sensor. The TTM interval is either read
automatically from the sensor settings or can
be specified manually.
Stressing influences (temperature, measure-
ment in extreme ranges) shorten the timer
interval.
Asymmetry
potential
The voltage which a pH sensor provides at a
pH of 7. The asymmetry potential is different
for each sensor and changes with age and
wear.
Buffer set Contains selected buffer solutions which can
be used for automatic calibration (Calimatic).
The buffer set must be selected prior to the
first calibration.
Buffer solution
Solution with an exactly defined pH value for
calibrating a pH meter.
