EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A 59
Alarm values during the calibration
If alarm values (see page 89) have been activated, they are also active during
the calibration. Alarm value monitoring is not active during the calibration if
the current signals have been configured to "Hold" (see above).
Plausibility check during the calibration
If the gas analyzer discovers implausible values during the calibration (e.g.
the end-point value is the same as the zero-point value), it aborts the cali-
bration and outputs status message 503 (see page 132). The values stored
for the last calibration remain in effect.
Wait until the warm-up phase has ended
The gas analyzer may not be calibrated until the warm-up phase has been
concluded.
Duration of the warm-up phase:
Uras26: approx. ½ hour without, approx. 2.5 hours with thermostat
Magnos206: approx. 2 hours
Magnos28: approx. 2 to 4 hours
Caldos27: approx. ½ hour
Caldos25: 1 to 4 hours, depending on the measuring range
Atmospheric pressure effect
If a pressure sensor (see page 26) for atmospheric pressure correction has
not been installed in the gas analyzer, the atmospheric pressure value must
always be checked before calibration and reset (see page 122) if necessary,
• if the height of the operating site of the gas analyzer has been changed
since the last calibration or
• if the atmospheric pressure effect on the measured value is too high.
