TEST 91

1. Connect RED clip and BLACK clip to the

indicated

test points in the question.

RED to

the first, BLACK to the second.

2. Start Test 91,04.500

Ohms.

3. Disphyed

reading is in ohms.

Less than

5 ohms is continuity.

If the resistance is over

4.500 ohms, STWICE-R

displays .9.9.9.9.

CONTINUITY

(RESISTANCE)

MULTIMETER

1. Set the voltmeter to an ohms scale of about

1,000 ohms.

2. Connect the RED and BLACK leads to the
