Filter Time Constant: Used to damp noisy signals. The higher the fil-
ter 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 after
calibration. During calibration plus hold-time, the signal outputs are
frozen (held on last valid value), alarm values, limits are not active.
Range: 0–6'000 Sec
See 5.3 Relay Contacts, p. 61
The instrument is equipped with an internal logger. The logger data
can be downloaded to a PC using the built-in RS232 interface.
The logger can save approx. 1500 data records. The Records con-
sists of: Date, time, alarms, measuring values, raw values, case tem-
perature, flow.
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).
Range: 1 Second to 1 hour
5 s 1 min
2 h 25 h
Clear Logger: If confirmed with yes, the complete logger data is de-
leted. A new data series is started.
