CAUTION: When test references are set up for the asset and Zero Start Override is active, the full target
voltage (displayed top right in the lower graph) will automatically be applied to the asset.
7. 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.
8. When you reach the target level, continue to hold the PTT button until the software generates a satisfactory Pulse
Count (displayed middle right in the Surge waveform graph). Typically, 10–15 pulses are sufficient to obtain a stable
waveform.
9. Release the PTT button when you have a satisfactory waveform.
10. If your active test configuration is set up to test coils in both directions, and AUTO ADVANCE is OFF, touch the Leads
Direction icon at the top to switch test direction from Lead 1–2 to Lead 2–1 then run the Surge test procedure
again. With AUTO ADVANCE ON, this will happen automatically.
11. Change test leads after each surge test completes and repeat until all coils have been surge tested.
NOTE: When you use a separate reference for each lead (L1 and L2), you must physically connect each
coil in the same manner to ensure that the proper reference applies to the lead that will have the surge
pulse applied. Properly correlating the references with the physical connection will ensure that your test
results are accurate across all coils.
12. Save results after completing your tests.

NOTE: If PD testing is enabled in coil mode and a PD event is detected, a red “PD” symbol will appear just
above the ACTIVE TEST button and a PASS/Fail result will be added to the test event record.
