    An RPM4 may have multiple ranges. Each Q-RPT in the RPM4 system has a default range which is its maximum span. The default ranges of the RPM4 A70M/A20M are 10 000 psi (A70M) and 3 000 psi (A20M). Additional ranges, lower than the Q-RPT’s maximum span, may also be created using AutoRange (see Section 3.3.4) or AutoTest (see Section 3.3.10).

    Measures pressure relative to atmosphere (zero is ambient pressure). Range is from zero gauge to full scale, full scale must be greater than zero. The RPM4 A70M/A20M-AF Q-RPTs measure pressure relative to a sealed vacuum reference and are intrinsically absolute. Gauge mode is accomplished by offsetting of atmospheric pressure with dynamic compensation for atmospheric pressure changes between offsets using an on-board barometer (see Section 3.2.2).

    OVERVIEW RPM4 A70M/A20M-AF was designed for maintenance free operation. No maintenance is required other than: • Regular AutoZeroing of quartz reference pressure transducers (Q-RPTs) (see Section 3.5.1). • Periodic calibration of Q-RPTs (see Section 5.3). • Adjustment of the on-board barometer (see Sections 5.2.2).

    AutoZero is used in normal operation. 5.3.2 EQUIPMENT REQUIRED The recommended calibration standard for the RPM4 A70M/A20M-AF Q-RPTs is a DHI PG7202 piston gauge with a DHI RPM4 A100K reference pressure monitor connected to the PG7202 as its external barometer. Contact DHI for additional information.

    Take care to avoid overpressure of the Lo Q-RPT (A20M with maximum pressure of 3 000 psi). The HPMS rear TEST port connects to both the A20M (3 000 psi) and the A70M (10 000 psi) Q-RPTs. Use the Lo RPT Isolation Valve on the HPMS front panel to isolate the Lo RPT when applying pressure to the Hi RPT (see Section 3.2.5).
