Setup ON/OFF Power Switch Figure 5 To power the meter on, move the Power Switch to the right as shown in Figure 5. Note: Before taking measurements, wait approximately 1 minute after powering up the meter.
  • Page 12 Scroll Right Figure 6 The following screen will appear on the LCD as shown below in Figure 7. Pressure=###.##psi < ###.##psi > High ###.##psi Figure 7 The real time pressure (psi) is displayed along with the operator’s specified Low and High range limits as shown above in Figure 7. The Low and High range limits are input into the meter’s non-volatile memory at the Setup stage, which will be explained in section 4.8 Setup.
  • Page 13 The High range limit indicator is a “>” symbol that is displayed in the upper right- hand corner. Refer to Figure 9. This indicator appears when the pressure reading is more than the acceptable High range limit value XXX.XXpsi. For example: If the High range limit is > 25.00psi and the actual pressure reading equals 25.01psi, then the High range limit indicator “>”...

    Use the same procedure to setup the probe sensitivity as was previously used for setting up the limits and median. Refer to Appendix E for the probe’s sensitivity value. 4.9 Powering off the meter To power off the meter, simply move the ON/OFF switch to the left as shown in Figure 24.
  • Page 20 Average pressure: For precise pressure readings, set the meter in averaged reading mode. Averaged reading mode is useful for determining the pressure levels of a particular point or the tanks overall output For a good starting point, set the number of samples to 10, and the interval to 1 second.
