1. Performing Custom Test
Press Custom Test when in the Tests tab.
Select the load (HL, PF, LL) and the phase.
If you press HL with all the phases (A+B+C), the load current will increase to 2.5A and
the meter will start to send pulses. In the following display, the meter sees a load of
873.75W (voltage x current x 3)
Note: If you wish to test only Phase A, select phase A in the Select active phase drop-
down window. If you wish to test only phase B, select the B phase and so on for
phase C. In the current example, only phase B is selected. The selection is shown on
the third line in the middle of the screen.
Press START TEST to start the test. The meter sends pulses and the internal electronic
standard of the MT-1/WT3 starts measuring the energy sent to the meter.
In addition to the test parameters appearing on the display, the operator can see the
voltage and current applied to the meter, the chronometer and the cumulated
energy registered by the electronic standard.
On this display, the internal electronic standard of the MT-1/WT3 shows that it has
registered up to now 3.93Wh (voltage x load x 3 x time/3600). When calculating Wh,
time is expressed in hours.
2. Test Results
The watthour measurement period ends automatically after the minimum time of
test by default, here >20 seconds. Then the load is removed automatically, and test
results are displayed
The test results show this meter has a percentage registration of 100.02% under a
2.5A load. By default, the test result is displayed in percentage registration. Test
results can be saved by clicking YES.
Please note that you can abort a test at any time.
