Calibration - HEIDENHAIN PWM 8 Operating Instructions Manual

7. Calibration

In general no maintenance is required for PWM, since there are no components that are subject to wear.
However, to ensure reliable and trouble-free operation we recommend to send your PWM 8 including the
interface boards (especially 11µApp and 1Vpp) every 2 years to HEIDENHAIN, Traunreut for calibration.
Note:
Calibration of the PWM always includes a software upgrade!
