Gas sampling and gas conditioning technology

4-1.1-ME

N O T E !

Adjust the flow meter FM1 to a flow rate above the demanded alarm value.
Because of breaking the outlet dew point (5°C) the total flow rate should not
pass the specified maximum value (see 2.).
The minimum flow rate is determined by the sample gas pump. This re-
quires the following minimum values:

N3 KPE:

approx. 60l/h;


N9 KPE: approx. 200l/h;


If the flow rate remains under the minimum value the pump membrane can
be premature destroyed by over pressure !


17.2 CHECK/CALIBRATION

turn switch to ‘Check’ (LED yellow); is available as contact outlet;

turn switch to ‘Test gas’ (LED yellow);

turn switch to ‘Zero gas’ (LED yellow);


After this calibration or checking the measuring range with zero gas can happen.

turn switch to ‘Span gas’ (LED yellow);


Now calibration or checking the measuring range with span gas can be started.

For returning to the measuring mode:

turn switch to ‘Sample gas’ (LED yellow);


If the analyser has reached the measuring range:

turn switch to ‘Measure’ (LED yellow).
