4 Operation
4.1 Sensors
4.1.1
Verification kits:
4.1.1.1
Verikit low:
Set the absorbance value of the verification filter “low” ac
-
cording to the calibration certificate.
Range: 0.0000–0.1000
4.1.1.2
Verikit high:
Set the absorbance value of the verification filter “high”
according to the calibration certificate.
Range: 0.1500–0.2000
4.1.2
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
4.1.3
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
4.1.4
Meas. Interval:
Measurement interval for disinfectants.
Range: 5 to 10 min
4.2 Relay Contacts

4.3 Logger
The instrument is equipped with an internal logger. The data can be
copied to a PC with a USB stick if option USB interface is installed.
The logger can save approx. 1500 data records. The records consist
of: Date, time, alarms, measured value, flow, zero, case
temperature.
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.
