METER IDENTIFICATION
BASIC TESTS
Setting Range Position
Select the largest value the multimeter can measure
within the test settings.
Example: If you’re testing 100V DC turn the Range
Selector knob to 200V DC, then the highest voltage
the meter can measure is 200V in that range.
Voltage Function AC – DC
Determine the current you’re testing AC or DC.
Select the largest value within the range you’re testing.
1. Insert the BLACK or ground probe to the
COM on the meter.
2. Insert the RED or positive probe to
the on the meter.
3. Touch RED probe to the circuit coming from
the power supply.
4. Touch BLACK probe to ground or the
negative (-) circuit.
5. Read the meter display for your results.
Note: If you don’t know positive (+) and which
side is negative (-), then arbitrarily connect the
RED test lead to one side and the BLACK to the
other. The multimeter automatically senses
polarity and will display a minus (-) sign when
negative polarity is measured.
WARNING: When measuring voltage be sure the
red test lead is in the terminal marked V. If the test lead
is in and Amp (A) or Milliamp (mA) terminal you may
be injured or the meter damaged.
DC Current Function
This meter measures DC current from 0 to 10A. If the
current exceeds 10A, the internal fuse will blow and
will need to be replaced. The capability of isolating
current drains and short circuits are some applications
for DC Current.
1. Insert BLACK test lead into COM test lead jack.
2. Insert RED test lead into “10A” test lead jack or
“mA” test lead jack.
3. Disconnect the circuit from power where you want to
measure current. Possible ways to do this are by
