On the Measurement Screen, status symbols display when the
analyzer fails to perform an action or fails a test.
Auto zero/Auto calibration
The Auto zero/Auto calibration symbol is a pre-warning which
indicates that an Auto zero/Auto calibration is required. This is
automatically performed by the analyzer when the measurements
are stopped. The measurements can be continued for a maximum
of half an hour while the symbol is on. Then the analyzer stops the
measurements and the Auto zero is performed.
Output Flow Fail
The Output Flow Fail symbol indicates that the exhaust sample
flow output is obstructed.
Low Flow
The Low Flow symbol indicates that the sample system input flow
is restricted.
Too Much Water in Filter Bowl
When there is Too Much Water in Filter Bowl assembly or the
water filter is clogged, this symbol displays. Wait until the analyzer
has removed the water from the bowl or replace the water filter.
