Sequence of calibration
The sequence of automatic recalibration, whether activated by pressing the appropriate key or via
the internal clock, is always the same and lasts approx. 8 minutes.
Start (clock or key)
Connecting the calibration gas
Purging the device (waiting time)
Taking measured values/
finding a mean value
Calculating the new parameters
Connecting the measuring gas
Purging the device (waiting time)
Accepting the current measured value
Test gas analysis
For the analysis of an external test gas connect the test gas cylinder to the gas inlet "C" (s. drawing).
To start the test gas analysis select the mode "Man. Test Gas" in coordinate M 12 and set it back to
"Test Gas OFF" for completion. In any case a test gas analysis can maximally last as long as
specified in coordinate M 13 as time limit (in minutes). Afterwards the EMC 500 switches back to
measuring gas analysis. The results of the test gas analysis are displayed in M 14 to M 24.
Maintenance
The EMC 500 is basically maintenance-free.
As in the case of every measuring instrument, you must make sure that it is supplied with clean and
dry gas only.
Drying and filtration units are available as options.
