To verify the differential pressure, perform the steps described in steps 6 through 12 above, except instead of clicking the
Calibration tab, click the Verication tab. You will be prompted to enter an applied value, and you will apply the same
pressure to the MVT, just as in the calibration process. The web interface will display a measured value and a percentage
of error. When you click Save, the measured values are written to memory.
Note Error is expressed as a percentage of the full scale of the MVT input range.
Placing the Scanner into Operation
To put the Scanner into operation:
1. Close the vent valve (Figure 2.19).
2. Open the equalizer valves.
3. Open the bypass/block valves to allow pressure to be supplied to both sides of the MVT.
4. Close the equalizer valves.
5. Open the vent valve (optional, you may choose to leave the vent closed).
