g. The display above shows the current ramp percentage of the test-level current. The Auto-Ohm
will ramp the test current from 0 (zero) amperes to the selected test current level in the selected
ramp time. The test current is automatically ramped up and down. This current ramp rate is
programmable from 5 seconds to 30 seconds. When the current reaches 100%, the next display
(shown in Figure 22.0) appears automatically. This display shows the resistance reading and the
remaining burn-time of the test.

h. The Auto-Ohm then ramps the test current back to zero. Figure 23.0 shows the final resistance
measurement and the test current at which the resistance was measured. After the result is
examined, press or turn the control knob for the REPEAT TEST menu.

i. To repeat the test, press then release the control knob. The Auto-Ohm repeats the test using the
same test current, ramp time, and burn-in time settings.
To exit this test mode, turn the control knob to select
the MAIN MENU.
From the Main Menu another test can be run. If all tests have been completed, turn off power to
the Auto-Ohm, disconnect test leads and power cable, and stow them. This completes the
procedure for performing the NORMAL test procedure.
NOTE
A CABLE ERROR message will be displayed on the Auto-Ohm LCD if the current
cables or sense cables are not connected as shown in Figure 8.0 to Figure 11.0.
