RESISTANCE AND CONTINUITY
04,500 OHMS
STEilCE-R TEST 91
1. Connect RED clip and BLACK clip to the
teminations
indicated in the question. RED to
the first, BLACK to the second.
2. Start Test 91,0-4.500
Ohms.
3. Displayed reading is in ohms. Less than 5
ohms is continuity.
If the resistance is over
4,500 ohms, STEXE-R
displays
.9.9.9.9.
Repair/replace wires (para. 4-90).
CONTINUITY (RESISTANCE)
MULTIMETER
. Set the voltmeter to an ohms scale of about
1,000 ohms.
!. Connect the RED and BLACK leads to the
connections stated in the question.
). Be sure to read the correct scale. Less than
5 ohms indicates continuity.
For an open circ
the meter should peg full scale (needle all the
way to the left).
