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
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
4.1.3
Meas. Interval:
Measurement interval for disinfectants.
Range: 1 to 12 Min.
4.1.4
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
installed.
Range: 0–14 pH
4.2 Relay Contacts
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. The records
consist of: Date, time, alarms, measured value, measured value
uncompensated, temperature, flow.
Range: 1 second to 1 hour
4.3.1
Log Interval:
Select a convenient log interval. Consult the table
below to estimate the max logging time. The logging buffer is
designed as circular buffer. If the buffer is full, the oldest data
record is erased to make room for the newest one.
If the logger interval is set to event driven, a data record of every
valid measurement is saved. The interval corresponds with the
measuring interval.
4.3.2
Clear Logger:
If confirmed with
yes
, the complete logger data is
deleted. A new data series is started.
