2. Press the TEST button. During the Ratio test, the instrument will
check for H/X reverse polarity, short (excessive current) etc. before
conducting Ratio test.
NOTE:
If the H/X is reversed, the instrument will display the error message
as in VT/PT test and terminate the test
If there were a polarity reversal, the Ratio would be blinking with a
negative sign. This means either the connections are reversed on a
given side or the transformer is wound backwards relative to the
marking
The test can be cancelled at any time by pressing the TEST button
during the operation
The CT test ramps up the voltage in steps. At the end of the test, it
ramps down the voltage
There are certain low mass, low ratio CT's for which the TR8703
may not be able to provide correct ratio. The error message will be
"High Excitation Current"
As in VT/PT, the CT test may be run as many times as needed by
pressing the TEST button.
The measurement records can be saved in Manual or Auto mode as in
VT/PT mode.
The CT remains active until the configuration is changed. Powering the
instrument down and turning it back on will not change the Test Type.
