PAS Systems International recommends having the calibration checked
once a year, or whenever it seems to be losing sensitivity. Instructions for
both wet bath and dry gas checking/calibrating are included in this manual.
You may also choose to send your PAS V into the manufacturer (PAS
Systems) to be calibrated.
