Caution CAUTION: Avoid excessive overpressure to the sensor! Externally mounted relief valves to provide overpressure protection are avail- able from Mensor as optional devices, and are highly recommended for very low pressure sensors (less than 10 psi). Caution CAUTION: It is recommended that a backup wrench be used when installing fittings or connections on the CPG2300. - Page 8 Portable Digital Pressure Gauge CPG2300 Series Notes Operating Instructions CPG2300 Series...

The current input option is capable of measuring current from 3 to 24 milliamps (mA). The calibrated range is from 4 to 20 mA. The CPG2300 also provides a 24V dc loop power source which can be turned on or off and that will power most transmitters. The CPG2300 current measurement is protected from over-current or high voltage up to 50V. - Page 34 Calibration Screen: The mA calibration screen allows zero and span to be ad- justed, the calibration to be reset to the factory defaults or the calibration password to be changed.
