EL3000 CONTINUOUS GAS ANALYZERS | OI/EL3000-EN REV. D 137
Test gas connection at the sample gas inlet during manual
calibration
If the test gas is connected directly at the sample gas inlet
during manual calibration, when the pressure switch is activated
the following message appears in the LCD display:
‘Error. Pressure switch has not detected any calibration gas!’
Check test gas flow and repeat calibration with .
This message can be bypassed by pressing  ESC.
Wait until the warm-up phase has ended
Analyzer module may not be calibrated until the warm-up phase
has ended.
Fidas24 – Substitute gas calibration
Example
Substitute gas calibration in the Fidas24 is described using the
‘Acetone measurement in room air’ example.
Acetone measurement in room air
Acetone (C

H
6
O) in higher concentrations cannot be filled in test
gas containers.
For this reason, the analyzer module is factory-set for calibration
with the substitute gas propane (C

) in N

.

Calibration
• Calibrate zero point with air (Component 1 or Component 2).
• Calibrate end point with test gas propane in N
2
.
Other measurement tasks
For other measurement tasks select the test gases and
measurement ranges in a similar manner according to the
sample gas composition.
