rated input voltage of 120. Refer to the nameplate<br />
of the transformer being tested and use input voltage<br />
shown.<br />
<br />
With Power Off:<br />
1. Connect the input leads and voltmeter to the<br />
transformer primary terminals.<br />
2. Connect the milliamp meter to the transformer<br />
high voltage terminals.<br />
3. (1) <br />
or adjust powerstat to read 120 volts on the<br />
volt-meter. Read the SHORT CIRCUIT mA on<br />
the milliamp meter and disconnect input plug.<br />
4. Connect the tube load in series with the transformer<br />
high voltage terminals.<br />
