6.6 Auto-Ohm Quick Test Procedure
The Auto-Ohm Quick Test mode is a preset test that runs a test at 100 Amps for 5 seconds. To
start a quick test, go to the RUN TEST option in the MAIN MENU. Press and hold the control
knob for 2 seconds. A short beep will be heard at which point the knob must be quickly released.
The Auto-Ohm will beep twice to acknowledge the quick test command has been accepted. Press
then release the control knob again to initiate the test. The Auto-Ohm will run a 100A test with a
5-second burn in time (Figure 34.0). The displayed test result will resemble Figure 33.0.
