Maintenance of Pressure and vacuum equipments

When the vacuum pressure falls to a predetermined level, a switch engages the pump to restore vacuum pressure; when the vacuum builds back up, the switch disengages and no further vacuum is created. Generally the pump is set to begin operation when the vacuum level of the system drops to 19 inHg (483 mmHg) and ceases

Ideally, the pressure range of the test instrument should be the same as the instrument tested. A digital test instrument with a range that falls within acceptable error rate may also be used. The frequency of calibration should be determined by the user according to criticality of the application and account for the many factors that contribute to the life of an instrument. These factors include, but are not limited to, vibration, pulsation, pressure spikes, pressure cycles, temperature and other environmental conditions.
