Air-IN gas input on the gas processing module. Here the calibration gas must
be applied without pressure. Proceed as follows:
-CO / NO / NO2 / SO2 calibration
(Important: Span gas must get pressure-free to the instrument!)
-Flow with span gas
-Wait for stabilisation of value
-By drift press <Enter>
-Set correct value with number keys
-Confirm input with <Enter>
-T. Gas / T. Air calibration
-Create reference temperature
-By drift press <Enter>
-Set correct value with number keys
-Confirm input with <Enter>
