3. Operation Power: The standard BetaGauge PIR is supplied with 3 AA batteries installed. If you purchased the optional 24Volt powered version, batteries are not installed. Connect a 24V power supply to the terminal block on the rear of the gauge, noting proper polarity. Do not install batteries when external power will be used. -

6. Set sample rate: This determines how often pressure is sampled and the display is updated. Choices are 0.5, 1, 3, and 10 samples/second. Note that 10/sec provides the fastest response time. 7. Set TARE. This allows you to set a constant offset value, which is then subtracted from the measured pressure. -

RS-232 Interface An RS-232 interface is standard on the BetaGauge PIR. Serial communication can be used for configuration, calibration, and to transfer measurement data from the gauge. For detailed specifications on the interface and software communication, see pages 14 and 15 in this manual. WARNING The RS-232 interface must not be used in hazardous areas. - Page 11 Media Compatibility All ranges except the compound range: Liquids and gases compatible with 316 stainless steel Compound range: clean, dry, non-corrosive gas Environmental Operating Temperature -10 °C to +55 °C (14°F to 131°F) Storage -20 °C to +70 °C (-4 °F to +158 °F) Humidity 10% to 95% RH Non-condensing Pollution Degree II Mechanical...
- Page 12 Appendix 1: BetaGauge P P I I R R Calibration Procedure Overview Calibration adjustment of the BetaGauge PIR is performed electronically via internal software with the case closed. There are no mechanical adjustments; all calibration commands and adjustments are done via the keypad, using the display to guide the user through the calibration process.
- Page 13 Procedure: Screens shown in this manual represent the displays shown with a 500 psi Gauge. The BetaGauge PIR will prompt the technician for the appropriate pressure at each calibration point. 500.00 CAL MODE Use the Pressure Standard to output 500.00 psi (100%). After the output has stabilized, press the ENTER key to continue.
