Plasma Gas Analyzer
61 02001001A_9
1.5 Automatic Calibration Mode
If the 4-20 mA analog output of the analyzer is set to
“HOLD”
mode in the configuration menu,
the analyzer waits for the
“TRANSFER DELAY”
before refreshing the 4-20 mA after the
re-span has been performed. This delay gives the time to purge the span gas out of the
system and avoid undesired bumps on the 4-20mA trending. The analog output remains at the
value calculated just before the beginning of the calibration.
