Note!
Analog value output during calibration
During calibration, the last TOC value is transmitted to the analog output and held until the
calibration value has been determined. The calibration value is then transmitted to the analog
output (or to analog output channel 1 in the two-channel version) until a new measured value of
the current sample is determined. During calibration, relay 4 (OPERATION CHECK) is open until
a new measured value is present during operation. If the analog output is used for control purposes,
this OPERATION CHECK signal can be used to declare the analog output as invalid.
