W-05 Autozero running Autozero is running …
Autozero process is performed,
started by user action or status input Wait until process stops
(30sec or 180sec max)
W-06 AZ val error
Autozero value out of
range Auto zero value is out of the internal
detector depending range Stop flow during auto zero.
Check detector installation
W-07 AZ fluct error
Autozero fluctuation out
of range Auto zero fluctuation is out of the
internal detector depending range
Stop flow during auto zero. Check
electrical installation, vibrations and
density.
