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
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
See 5.3 Relay Contacts, S. 75
The instrument is equipped with an internal logger. The data can be
downloaded to a PC by Hyperterminal if option "HyperTerminal in-
terface" is installed.
The logger can save approx. 1500 data records. Records consists
of: Date, time, alarms, measured value, measured value uncom-
pensated, temperature, flow.
Range: 1 second to 1 hour
Log Interval: Select a convenient log interval. Consult the table be-
low to estimate the max logging time. When the loggin buffer is full,
the oldest data record is erased to make room for the newest one.
