8. The M4000 is now ready to measure. The message “Set Test Voltage, Line
(x), Then Press F3 To Measure”, appears (where (x) is the selected line
number).
9. When you have set the external source to the desired voltage, press the F3
key. The message, “Do not change voltage - collecting data” appears.
10. When the message, “Test Done, Line (x)”, where (x) is the selected line
number, press the F5 key to accept results. The mA, Watts, Percent Power
Factor, and Capacitance/Inductance is recorded on the clipboard sheet.
11. At this point, if your test was a Specimen Test, you could run the Setup
Correction Test for this line (x). To do this, repeat steps 5 through 10,
selecting the same line number, and selecting Setup Correction Test. Since
performing the Setup Correction Test requires removing the high voltage
cable from the specimen, it will be practical to perform a series of
Specimen Tests first, and then go back, remove the high voltage cable
from the specimen, and perform a series of Setup Correction Tests
corresponding to the Specimen tests. If the losses of the High Voltage
cable and transformer can be guarded, it is not necessary to perform the
setup.
12. Once you have pressed F5 to save the Setup Correction Test results, the
line(s) that contain both the Specimen Test and Setup Correction Test will
be check-marked in the CR column.
13. You now have the option of repeating your tests in the reversal mode.
Simply repeat steps 5-12, always selecting the Reversal mode instead of
the Normal mode. When finished, you will have done either two tests per
line (no reversal tests made) or four tests per line (including reversal tests).
If testing indoors, Reversal Tests are not likely to be necessary.
