7.2 Calibration / validation
This mode is intended to support calibration and validation according to IEC 60974-14 Arc welding sys-
tems – Calibration, validation and consistency test.
To validate the nominal value specification, the current nominal value is displayed that can be set using
the rotary transducer. The actual values of current and voltage are displayed to calibrate the actual value
displays. The selection takes place in the system settings menu > see 5.4.4.5 chapter.
