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
Interval fac
: The measuring interval of “Free available chlorine” can
be set according to the process requirements.
Range: 0–12 min
4.1.4
Interval tc2
: The measuring interval of “Total chlorine 2” can be set
according to the process requirements. If the interval is set to 0 min
only fac is measured.
Range: 0–60 min
4.1.5
Default pH
: If the pH value of the sample is known it can be entered
in this menu. This menu only appears if the pH option is not in-
stalled.
Range: 0–14 pH

4.3 Logger
The instrument is equipped with an internal logger. The data can be
copied to a PC with an USB stick if option USB interface is in-
stalled.
The logger can save approx. 1500 data records. Records consists
of: Date, time, alarms, measuring values, temperature, flow.
Range: 1 Second to 1 hour
4.3.1
Log Interval:
Select a convenient log interval. Consult the table be-
low to estimate the max logging time. When the login buffer is full,
the oldest data record is erased to make room for the newest one.
