Sensor standardization
Operating modes • Entry of cell factor with simultaneous display
of conductivity and temperature
• Input of conductivity of calibration solution
with simultaneous display of cell factor and
temperature
• Product calibration
• Zero point adjustment
• Temperature probe adjustment
Adm. cell factor 00.100 ... 19.999

Sensor monitoring Monitoring of primary coil and its lines
Sensocheck for short circuit and of secondary
and its lines for open circuit
Sensoface Provides information on the sensor condition
(zero point, Sensocheck)
Sensor monitor Direct display of measured values from sensor
for validation (resistance / temperature)
