4 Operation
4.1 Sensors
4.1.1 Filter Time Constant: Used to damp noisy signals. The higher the
filter time constant, the slower the system reacts to changes of the
measured value.
Range: 5–300 Sec
4.1.2 Hold after Cal: Delay permitting the instrument to stabilize again af-
ter calibration. During calibration plus hold-time, the signal outputs
are frozen (held on last valid value), alarm values, limits are not ac-
tive.
Range: 0–6‘000 Sec
4.1.3 Faraday Parameter
4.1.3.1 Mode : Can be set to Interval, daily, weekly or off. If Mode is set to
“Off”, no further settings are available. The Faraday Verification has
to be started manually.
4.1.3.20 Interval : The interval can be set between 1h and 12h
4.1.3.21 Start Time : Start time appears if Mode is set to daily, how to set the
start time see 5.3.2.341, p. 84 .
4.1.3.22 Calendar : Calendar appears if Mode is set to weekly, how to set
the Calendar see 5.3.2.342, p. 85 .
4.1.3.3 Delay : during Faraday Verification plus the delay time the signal
and control outputs are held in the operating mode programmed
below.
Range: 0–6’000 Sec.
4.1.3.4 Signal Outputs : Select operating mode of the signal output:
4.1.3.5 Output/Control : Select operating mode of the controller output:
Cont.: Signal outputs continue to issue the measured value.
Hold: Signal outputs hold the last valid measured value.
Measurement is interrupted. Errors, except fatal errors,
are not issued.
Off: Signal outputs are switched off (set to 0 or 4 mA).
Errors, except fatal errors, are not issued.
Cont.: Controller continues normally.
Hold: Controller continues based on the last valid value.
Off: Controller is switched off.
