DMOM-100/200 Series 2 Operating Procedures

Rev 2, 2009

7.7 Running an Automatic Test Procedure
The Automatic Test Mode allows the user to initiate a test by applying the sense cable across the
resistor 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
DMOM’s working memory. The user can save up to 96 readings per test record. The DMOM
Flash EEPROM can store 63 test records.
The following procedure describes the steps to measure an unknown resistance using Automatic
Test Mode.

NOTE

• 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.

• Hand spikes (see Figure 3.0) are designed specifically for this application.

STEP

ACTION

DMOM DISPLAY

6-1

Press key # 1 (RUN TEST) on the START
MENU. The TEST SELECTION menu
will appear (shown at right).

6-2

Press key # 2 to select the AUTOMATIC
TEST option. The SELECT TEST
CURRENT menu will appear. The DMOM-
100 menu will contain 5 options. The
DMOM-200 menu will contain 6 options.
Press the corresponding key for the desired
test current. For this example, select key # 4,
(100A) then go to step 6-4.
For a CUSTOM test current, press key # 5
(key # 6 on DMOM-200), then go to step 6-
3.

Note

The burn-in time is set for 5 seconds

in the Automatic Test.

6-3

Using the keypad, enter the CUSTOM test
current level (in 1 amp steps). After entering
the value, press the ENTER key, then go to
step 6-4.
For this example, we used a 100A test
current.

SELECT TEST CURRENT:
1. 10A

2. 25A

3. 50A

4. 100A
