2.3 Example: How to perform a calibration
An external calibration may be performed via the PLC inputs and outputs. For this
purpose, one of the inputs needs to be configured to “CAL”, another needs to be set to
“CAL AIR”. The external calibration is always performed for the enabled gas with the
highest gas no. The test leak rate used is the test leak rate which has been used for the last
external calibration performed.
