INSTRUMENTS CIRCUIT
DC VOLTAGE O-45 VOLTS
STE/lCE-R TEST 89
1. Connect RED clip to the indicated test point,
BLACK clip to negative or ground.
2. Start Test 89. DC Volts.
3. Displayed reading is in volts.
BAITERY VOLTAGE

04.500 OHMS
STEkE-R
TEST 91
1. Connect RED dip and BLACK clip to the
indicated terminals in the question. RED to the
first, BLACK to the second.
I
2. Start Test 91,0-4,500 Ohms.
3. Displayed reading is in ohms. Less than 5 ohmr
is continuity. If the resistance is over 4,500
ohms, STEIfCE-R displays .9.9.9.9.
CONTINUITY (RESISTANCE)
MULTIMETER
I
1. Set the voltmeter to an ohms scale of about
1,000 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 continufty. For an open
circuit, the meter should peg full scale
(needle all the way to the left).
