Display:
Graphic display
Accuracy:
±1% based on the measuring range end value in the lower range 0...1.000mg/l
Temporary deviations of 10% of the measuring value can be caused by high
frequency irradiation.
Data logger:
continuous data logger, adjustable interval
for 1,000 measuring values (3,000 measuring values as an option
Measuring point data logger for 200 measuring values (TouchMemory system)
Data interface:
RS 232
Recorder output:
One output 0(4) ... 20mA
for concentration:
0…1.000 mg/l
0... 20.00 mg/l
to be set to a fixed value or automatic changeover
and detection of the measuring range
IMPORTANT NOTE!
Connection of a recorder with a grounding potential at the measuring reference
point (GND) constitutes an illegal operating status, where signal corruption is
possible due to potential and hum loops.
The recorder cable must not be longer than 3 metres.
