Sensor standardization
Operating modes • Entry of cell factor with simultaneous display
of conductivity and temperature
• Entry of conductivity of calibration solution
with simultaneous display of cell factor and
temperature
• Product calibration
• Zero adjustment
• Temperature probe adjustment
Permissible cell factor 00.100 ... 19.999
Permissible transfer ratio 01.00 ... 199.99

Sensor monitoring
Sensocheck • Monitoring of primary and wiring for
short circuit
• Monitoring of secondary and wiring for
open circuit
Sensoface Provides information on the sensor condition
(evaluation of zero point, Sensocheck)
Sensor monitor Sensor monitor for validation of sensor and
complete measured-value processing
