Program List and Explanations
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
4.2 Relay Contacts
4.3 Logger
The instrument is equipped with an internal logger. The logger data
can be:
downloaded to a PC by Hyperterminal or SWAN Terminal if
option “HyperTerminal interface” is installed.
copied to a PC with an USB stick if option USB interface is in-
stalled.
The logger can save approx. 1500 data records. The Records con-
sists of: Date, time, alarms, measuring value, measuring value un-
compensated, case 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).
Range: 1 Second to 1 hour
4.3.2
Clear Logger:
If confirmed with
yes
, the complete logger data is de-
leted. A new data series is started.
