Program List and Explanations
A-96.250.871 / 120417 53
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

of: Date, time, alarms, measured value, measured value uncom-
pensated, temperature, flow.

4.3.1 Log Interval: Select a convenient log interval. Consult the table be-
low to estimate the max logging time. When the logging buffer is
full, the oldest data record is erased to make room for the newest
one (circular buffer).
4.3.2 Clear Logger: If confirmed with yes, the complete logger data is de-
leted. A new data series is started.
