AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 135
Warm-up phase
Warm-up phase
The duration of the warm-up phase depends on which analyzer module is
installed in the gas analyzer.
Analyzer module Duration of the warm-up phase
Caldos25 1.5 hours
Caldos27 30/60 minutes for class 1/2 measurement ranges
1)
Fidas24 ≤ 2 hours
Fidas24 NMHC ≤ 2 hours
Limas11 IR Approx. 2.5 hours
Limas21 UV Approx. 2.5 hours
Limas21 HW Approx. 4 hours
Magnos206 ≤ 1 hour
Magnos28 ≤ 1 hour
Magnos27 2 to 4 hours
Uras26 Approx. 0.5/2 hours without/with thermostat
ZO23 Approx. 15 minutes
1) See "AO2000 Series" data sheet for class details.
NOTES
The warm-up phase can take longer if the gas analyzer was not brought to
room.
During the warm-up phase measurement values can be outside the ranges
specified in the data sheet.
Warm-up phase duration
The warm-up phase is deemed to be over when the measured value drift
indication is acceptable. This depends on the size of the measurement
range.
NOTE for Fidas24
Unused sample gas lines and sampling probes can release hydrocarbons
after the first start-up over a longer period. Therefore, it can take a longer
time until the measured value drift has reached an acceptable value.
