Example 4: Custom Test – 2S Electromechanical Meter

Accessory
The Custom mode involves applying a 30 A load for 10 revolutions. The Metercam is
used for this test.
1. Installing the Metercam and the Cable
Install the Metercam and the cable:
1.
Roughly align the Metercam's 0.5" field view disk zone with the meter disk.
2.
Press the Metercam's four corners onto the meter cover hard enough for
the suction cups to grip.
Notes: Make sure that the four suction cups stick perfectly to the meter
cover for the entire duration of the test. If necessary, lightly moisten the
inside of the suction cups.
3.
Insert the red end of the socket's coiled cable into the Metercam's bottom
right connector. See Fig. 2.4.
2. Disk Detection
Once the unit detects the Metercam's presence, a load is automatically applied to
the meter to spin the disk. The Metercam starts the scanning process to detect the
meter disk's position. The red LED turns on when the scanning starts. The green LED
turns on when the Metercam has found the disk's position. 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 performed automatically
to estimate the meter's Kh. If the estimated Kh found is already stored in the remote,
it is selected for the test.
3. Initialization
On 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.
