CALIBRATING TEST EQUIPMENT
Periodically calibrate test equipment (pressure gauges, weight scales, flowmeters, etc.) to
ensure the reliable operation of the Companion 1000/T. Use your prior experience to
determine calibration frequency for test equipment. Using a default six-month schedule
is typically acceptable; however, check test equipment with a high usage rate once a
month. Once you have begun using the piece of test equipment, you may adjust the
calibration schedule. If, for example, you begin calibrating your test pressure gauge
every six months and it is repeatedly out of calibration when you check it, you should
