TM 9-2320-280-20-1 REFERENCE INFORMATION INSTRUMENTS CIRCUIT 0-4500 OHMS STE/ICE-R TEST 91 I 1. Connect RED clip and BLACK clip to the indicated terminals in the question. RED to the first, BLACK to the second. 2. Start Test 91, 0-4500 ohms. 3. Displayed reading is in ohms. Lees then 5 ohms is continuity. It the resistance is over 4500 ohms, STE/ICE displays “9.9.9.9.” CONTINUITY (RESISTANCE) MULTIMETER 1. Set the voltmeter to an ohms scale of about 1000 ohms. 2. Connect the RED and BLACK leads to the connections stated in the question. 3. Be sure to read the correct scale. Less than 5 ohms indicates continuity. For an open circuit, the meter should peg full scale (needle all the way to the left). 2-379
