12. Select "Run Calibration" which will cause the prover piston to be
returned to the upstream position and start the draw sequence.
See resulting Prover Status screen as shown below.
After selecting Run Calibration following screen appears.

13. Water should now be draining into the wastewater container until the
flag reaches the first optical (volume) switch. When the first optical
switch is reached, the signal will be sent to the SVP controller to switch
the valves (turn the SV2 valve OFF and turn the SV1 valve ON). At that
time the water will start flowing into the Test Measure.
14. Record the prover pressure (Pp) at P1 while only the water draw
valve is open (SV1). Valves V5 and V6 must be closed while recording
this pressure, which is the pressure at the start and the end of
volume switching.
15. Record temperature (Td) at T2, which is the detector temperature,
by opening the drive cover and placing the thermometer midway
between volume switches, which is the location of the switch bar
temperature transmitter thermowell.
16. Record fluid temperature (Tp) at T1.
17. When the flag reaches the second optical (volume) switch, the draw
valve (SV1) is turned OFF and the bypass valve (SV2) is turned ON.
Carefully record scale reading (SR) and test measure temperature
(Ttm) at T3.
18. After all data is collected, drain the test measure.
19. Repeat steps 12 through 18 as necessary to obtain the required
number of well repeating runs (including one run at 25% flow
rate variance).
Please note that a log will be saved with start time and sweep time
after each calibration run.
20. Once you have completed the calibration, select the "Exit Calibration"
menu which will turn the bypass valve (SV2) OFF.
