5.1 Foreword
Calibration of the device is essential to ensure a correct measurement. Additionally,
calibration allows also the operator to detect a possible problem with the module or the
module’s environment.
After a calibration, it is possible to perform a check (which is recommended by ATS-ERS
guidelines) in order to verify the quality of the calibration and the accuracy of the
measurement.
The table below summarises the calibrations which have to be performed on Ergocard CPX
module.

The module should be turned on at least 20 minutes before performing the
calibration.
This allows for adequate warmup time for the analyzers.
