d. Connect a hand pump or funnel to the tting.

e. Pour ll liquid into the funnel or pump it into the cold leg, tapping the cold leg occasionally to dis-

lodge any bubbles.

f. Observe the pipe tee/condensate pot and stop pouring when the ll liquid is visible at the top and no

air bubbles can be seen.

g. Remove the tting from the vent of the MVT and quickly replace the vent screw and tighten.

h. Close the blowdown valve or replace the lling plug from one of the pipe tees/condensate pots.

i. Repeat steps a through h for the other cold leg.

9. To eliminate an offset of the differential pressure reading, open the equalizer valves on the block manifold,

remove the caps from the seal pots, and adjust either seal pot vertically to bring the water levels to the exact

same elevation.

10. Perform a manifold leak test as described on page 55.

11. Verify the zero offset, if required (and other calibration points, if desired). See the ModWorX™ Pro Soft-

ware User Manual, Part No. 9A-30165025, for complete instructions. See also Zero Offset (Static Pressure

or Differential Pressure), page 56, Static Pressure Calibration and Verication, page 56, and Differential Pres-

sure Calibration and Verication, page 57.

CAUTION Do not put the Scanner into operation until the valves are positioned properly so that

pressure is supplied to both sides of the MVT. For instructions on proper valve positions,

see Placing the Scanner into Operation, page 58.
