DPG 2400 Series 8. Calibration The DPG 2400 automatically adjusts the pressure readings for the effects of tempera- ture within the calibrated range (see Section 4, Specifications). Thus, a calibrated DPG 2400 operated within its temperature band, and with proper zero and span settings, will provide accurate pressure measurements. - Page 32 Setup for Gauge or Differential Pressure PRESSURE SUPPLY LINE REGULATOR Computer (optional) METERING VENT VALVE SHUT-OFF VALVE VOLUME CONTROLLER RS-232 RS-485 ATMOSPHERE PRESSURE PRESS DPG 2400 PRESSURE PRESSURE GAUGE STANDARD REFERENCE Figure 8.2 - Calibration Setup Operating Instructions DPG 2400 Series...
