Calibration of ULTRAMAT 23

The Set CEM CERT system is configured so that the ULTRAMAT 23 analyzer (option
C10, C20, C30) automatically performs an AUTOCAL with ambient air every 24 hours.
This adjusts the zero point and sensitivity of the IR channels. The sensitivity of the O
channel (if present) is also adjusted. The timing for this can be set. (Menu → Calibration
U23 → Press AUTOCAL display)
In addition, the full-scale value must be readjusted every 6 months with calibration gas.
BEFORE calibration of the full-scale value, we recommend carrying out an AUTOCAL
with ambient air. Allow approximately 30 minutes for a complete calibration and take this
into account if you have to guarantee regulatory availability of the AMS or provide half-
hour averages.
