Note!
• Always synchronise calibration and flushing time.
• Carry out flushing with standard cleaning solution approx. 3-4 hours
before the next calibration.
• Flushing with special cleaning solution (e.g. hydrochloric acid) has a lasting effect on calibration.
Therefore, carry out this cleaning 3-4 hours after calibration.
Date of the
1st Calibration
01.01.96 00:00... 31.12.95 23:59
Time of 1st calibration (DD.MM.YY, time hh.mm). After
each change the instrument does not wait for the
calibration interval. If the calibration is to start
immediately, set the time in the past.
Analysers are delivered pre-calibrated.
– Start 1st calibration 2 hours after the initial start-up at
the earliest (warm-up phase)
– Set the time to 8:00 to reproduce impacts on
calibration in the curve.
– If you have started a calibration manually, you should
re-define the time of the 1st calibration because the
interval is dependent on the last calibration.
Calibration interval
0 ... 720 h
48 h
Time between two calibrations.
The "0 h" setting stops calibration.
Recommended: calibration interval of 48 ... 72 h.
Calibration solution
NO-A: 10 ... 500 μ g/l / 250 μ g/l
NO-B: 0.10 ... 1.00 mg/l / 0.50 mg/l
NO-C: 0.20 ... 3.00 mg/l / 1.50 mg/l
Concentration of the calibration standard.
Select a standard, whose concentration is in the upper
third of the measuring range.
Date of the
1st flushing
01.01.96 00:00... 31.12.95 23:59
Time of 1st flushing (DD.MM.YY, time hh.mm). After
each change the instrument does not wait for the
calibration interval. If the flushing is to start immediately,
set the time in the past.
– Set the time to 4:00 to reproduce impacts on flushing
in the curve.
– If you have started flushing manually, you should
re-define the time of the 1st flushing because the
interval is dependent on the last flushing.
Flushing interval
0 ... 720 h
48 h
Time between two flushings.
The "0 h" setting stops cleaning.
Flushing hold on
0 ... 60 s
60 s
Dwell time of flushing solution in the
pump-mixer-photometer line.
Recommended: 30 ... 60 s.
1) All channels set to 0 means, the channel selection is provided by an external device. All channels set to 1 means, alterning beginning with channel 1.
