Amprobe AC50A - Manual (Page 12)

Calibration Interval
We suggest a calibration interval of one year. If the instrument is used
very often or if it is used under rough conditions we recommend shorter
intervals. If the instrument is used only a few times a year, the calibration
interval can be extended to 3 years.
