Manual Coil Testing Processes Overview
NOTE: This process is written from the perspective of using a test configuration with test references
assigned as described in “Setting up References for Surge Testing” on page 93.
1. With the test leads properly connected to the asset, ensure that Coil #1 is displayed in the top middle field. This
is the number of the coil you are presently testing. You can select the coil being tested manually after each coil is
tested, or you can turn on the AUTO ADVANCE ON/OFF button found in the lower right corner to have the software
advance to the next coil automatically.
1. If AUTO ADVANCE is OFF and this number is not advanced after a test, results will be overwritten for the currently
selected coil. This process example continues with AUTO ADVANCE ON.
2. With the ACTIVE TEST button set to RLZ, press the Push-to-test (PTT) button on the top left of the ADX front panel
for a couple of seconds then release. All low-voltage tests will be run.
3. The LEADS ENERGIZED indicator (middle right) flashes to alert you that voltage is being applied. LEDs on the ADX
front panel also light to indicate the leads energized.
4. Values for the RLZ tests will be plotted in the upper graph. Change test leads to the next coil and repeat until all
coils have been tested for RLZ.

5. When all coils have been tested for RLZ, switch the ACTIVE TEST button to SURGE and set the coil to number 1.
6. Press and hold the Push-to-Test button on the top left of the ADX front panel to run a surge test.
