DC VOLTAGE o-45 VOLTS
STVICE-R TEST 89
I
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 vofts.
BAlTERY VOLTAGE
MULTIMETER
1. Set the voftmeter to a DC vofts scale of at least
40 volts.
2. Connect the RED lead to positive and the
BLACK lead to negative.
3. Be sure to read the correct scale.
RESISTANCE AND CONTlNUlIY
04,500 OHMS
STUICE-R TEST 91
1. Connect RED clip and BLACK clip to ttte
indicated terminals 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, STEIICE-R displays .9.9.9.9.
CONTlNUlTY (RESISTANCE)
MULTIMETER
1. Set the voltmeter to an ohms scale of about
1,000 ohms.
2. Connect the RED and BLACK leads to the
connectiins
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).
