3.2 Setting the Test Voltage
The ATRT-03 S2 offers three test voltages, 8 Vac, 40 Vac, and 100 Vac. The unit always defaults
to 40 Vac at power-on. The 8 Vac test voltage is for testing transformers which require low test
voltages, such as metering Current Transformers (CT’s). For metering CT’s, higher voltages may
drive the CT’s into saturation, thus giving invalid results. The 40 Vac test voltage is
recommended for testing power transformers. The 100 Vac test voltage is recommended for
testing power transformers in noisy environments. Follow the steps below to set the test
voltage:
a. Turn on the unit and start from the “ START-UP” menu:
Press the [2] key (SETUP).
NOTE
You can select menu options by typing the corresponding option number using
the alpha-numeric keypad or by using the control knob. To select menu
options using the control knob, turn the knob clockwise or counter-clockwise
to highlight the next or previous menu item respectively. Once the desired
menu option is highlighted, push the control knob to select it.
b. The following screen will be displayed:
