Autocalibration
The flow of calibration gas is enabled during the
purging time. The time parameterized under
identifier 2 is also used as the prepurging time
for the sample gas following the calibration.
Identifier: n
1 = zero gas
2 = calibration gas (1)
3 = calibration gas 2 (option)
4 = calibration gas 3 (option)
5 = calibration gas 4 (option)
6 = all calibration gases (option)
Identifiers 3 to 5 are only relevant if 4 calibra-
tion gas connections are present.
The corresponding measuring range is not
calibrated if the purging time = 0.
Factory setting: 1 min for all gases
The purging time is output on the display in
minutes.
Identifier: n =
1 = zero gas
2 = calibration gas 1
3 = calibration gas 2
4 = calibration gas 3
5 = calibration gas 4
Identifiers 3 to 5 are only relevant if 4 calibration
gas connections are present.
The hours and minutes up to the next autocal are
output in succession in the display.
