6.4 Run Automatic Test Procedure
Automatic Test Mode allows the user to initiate a test by applying the sense cables across the
resistive load. This feature is handy when the user wants to take multiple resistance readings of
the same load or of different loads in the same current path.
The burn-in time for Automatic Test is set for 5 seconds. The resistance reading is stored in the
ATO’s working memory. The user can save up to 96 readings per test record. The ATO Flash
EEPROM can store 63 test records.
The following procedure describes the steps to measure an unknown resistance using the
Automatic Test Mode.
NOTE
The current cables should be connected across the resistive load to establish the current path.
Removing and reconnecting one or both sense cables starts a new test.
