Omega Vehicle Security IP210 manual Calibration, Air Supply + to Maximum Signal

11. Calibration

When the instrument is first installed , or after a long period of downtime, a moderate zero shift is normal. This is due to the rubber diaphragms which are stretched by the internal springs. After a few operations, the instrument will settle into its normal operating condition. It is recommended that, under these circumstances, instruments should be exercised by alternately applying zero and full scale signals several times. Zero calibration should then be carried out.
