Single Phase Test Procedure
NOTE:
Unlike the three phase configuration, the single phase configuration uses each
test pulse LED to display the energy measured for three current inputs (see Table
6.2).
1. All circuits and equipment must be de-energized.
2. Connect one line of the potential source to the three "V~" inputs and connect the
other line to the "V-Ref" input and "GND."
3. Connect power to the "L" and "N" connections.
4. Monitor the #1 test pulse by placing the photo detector over the #1 LED.
5. Connect the current input to the first pair of current terminals associated with the
test pulse LED being monitored. Make sure that no other current inputs (refer to
Table 6.2) are connected.
6. Energize the Standard and the MP200 unit. To assure accuracy, both must be on for
a minimum of 30 minutes.
7. Energize the sources and wait for the outputs to stabilize before starting the test.
8. Start the test as per the appropriate procedure for the Standard used.
9. When the test is completed, de-energize the sources.
10. Remove the current connections to the MP200 unit and connect them to the sec-
ond current input pair for the test pulse LED being monitored.
11. Energize the sources and wait at least 5 seconds before starting of test.
12. Start the test as per the appropriate procedure for the Standard and/or compara-
tor used.
13. When the test is completed, de-energize the sources.
14. Remove the current connections from the MP200 unit and connect them to the
third current input pair for the test pulse LED being monitored.
15. Energize the sources and wait at least 5 seconds before starting of test.
