1)
0 4 hrs Measure
1) Cycle time factory-set to 4 hours
2) Post-purging time factory-set to 150 sec. For an analyzer system with Probe F,
this period must be as short as possible (to be determined during start-up)
3) 1x pressure impulse 2 sec, 1x interrupt 2 sec
4) 1x pressure impulse 2 sec, 1x interrupt 2 sec, 1x pressure impulse 4 sec
5) Calibration valve on = "Measure", calibration valve off = "Calibrate"
6) Only in version with VOC analyzer AO2000-Fidas24:
open = sample gas path open, closed = relaxation against atmosphere
7) not in a system with Probe 2, Probe F
8) 3x interrupt 2 sec, 2x pressure impulse 2 sec
9) 3x interrupt 2 sec, 2x pressure impulse 2 sec, 1x pressure impulse 4 sec
