is displayed on the lower portion of the screen. “PRESS ANY KEY TO STOP
TEST.”
At the completion of the test, TEST RESULT 1 screen is displayed containing the
measured turn ratio, ratios for multiple windings, and polarity (additive or
subtractive) of the transformer, if function is activated on the SYSTEM SETUP
menu. Letter "A" or "S" in the parentheses indicates the expected polarity of the
transformer.
TEST RESULT 2 screen is displayed by pressing the right scroll key, containing
the following information: Test Number, Vector Group, Phase displacement
between high side and low side windings, Excitation current (no-load), DC
winding resistance of the high side and the low side(s), if function is activated on
the SYSTEM SETUP menu. When "N/A" is displayed for resistance, it means the
resistance value is above the specified range.
Pressing 1 in the TEST RESULT 2 screen, one can provide HEADER information
such as, Company name, Substation name or location, Manufacturer name,
Transformer rating, Temperature, %RH and Operator’s name. This information
will be available for the test report when printed. In addition, one can print the
HEADER from this screen or return to TEST RESULT 2 screen.
From the TEST RESULT 2 screen, one can also select the following by pressing
the appropriate number: Print the test result (on an optional printer) by selecting
