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 91.9-4.5Ou Ohms.
3. Displayed reading is in ohms. Less than 5 ohm
is continuity.
If the resistance is over 4.500
ohms, WE/ICE-R
displays .9.9.9.9.

CONTlNUlTY (RESISTANCE)
MULTIMETER
1. Set the voltmeter to an ohms scale of about
1 .fIOO 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).
