Example 4: Custom Test - 2S electromechanical meter

Accessory:
The Custom mode consists in applying a 30A load during 10 revolutions. The
Metercam is used for this test.
1. Installing the Metercam and the cable
Install the Metercam and the cables:
1.
Roughly align the 0.5" field view disk zone of the Metercam with the meter
disk.
2.
Press the four corners of the Metercam onto the meter cover hard enough
to allow the suction cups to take hold.
Notes: Make sure that the 4 suction cups stick perfectly on the meter cover
during the entire test. If necessary, lightly wet the inside of the suction
cups.
3.
Connect the coiled cable with the red ends from the socket to the bottom
right connector of the Metercam. See Fig. 2.4.
2. Disk Detection
Once the unit detects the presence of the Metercam a load is applied automatically
to the meter to spin the disk. The Metercam starts the scanning process to detect
the position of the meter disk. The red LED turns on when the scanning starts. The
green LED turns on when the Metercam has found the position of the disk. Finally,
the red LED turns off when the black flag is found on the disk and turns on only when
the black flag passes in front of the Metercam.
Once the Metercam has found the black flag, a self- test is done automatically to
estimate the Kh of the meter. If the estimated Kh found is already stored in the
remote, it is chosen to do the test.
3. Initialization
In the test page, select Custom Test to go to the Tests tab.
At the top right of your screen, check that the Kh is 7.2.
