Operation
AC/DC Voltage Measurements
WARNING:
Observe all safety precautions when working on live voltages.
1. Set the rotary function switch to the proper ACV or DCV range. If the range is
not known, start at the highest range and then move to a lower range
if necessary.
2. Insert the black test lead into the negative input jack and the red test lead
into the positive input jack. For DC measurements, the red test lead should
be connected to positive voltage and the black test lead should be connected
to negative voltage.
3. Connect the test leads in parallel to the circuit under test.
4. Read the voltage on the display.
Resistance Measurements
WARNING:
Never test resistance in a live circuit.
1. Set the rotary function switch to the 10x or 1000x OHMS position.
2. Insert the black test lead into the negative input jack and the red test lead
into the positive input jack.
3. Touch tip of the black test probe and the tip of the red test probe to each
other. Adjust the OHMS ADJ so the display reads zero (0) ohms.
4. After zeroing, touch the test probe tips across the circuit or component
under test. It is best to disconnect one side of the device under test so the
rest of the circuit will not interfere with the resistance reading.
5. Read the resistance on the display. Multiple the resistance reading by 10
when in the 10x range and multiple the resistance reading by 1000 when
in the 1000x range.

Operation
DC Current Measurements
WARNING:
Observe all safety precautions when working on live voltages.
Do not measure current on circuits that exceed 250V.
1. Set the rotary function switch to the 500µA, 10mA or 250mA DCA range.
If the range is not known, start at 250mA and then move to a lower range
if necessary. Do not exceed 250mA.
2. Insert the black test into the negative input jack and the red test lead into
the positive input jack.
3. Disconnect power from the circuit under test and then open up the circuit
at the point where you want to measure current.
4. Touch the tip of the black test probe to the negative side of the circuit. Touch
the tip of the red test probe to the positive side of the circuit.
5. Apply power to the circuit.
6. Read the current on the display.
Battery Test
1. Set the rotary function switch to the 1.5V BATT position if testing AA, AAA or
1.5V button cell batteries. Set the rotary function switch to the 9V BATT position
if testing 9 volt batteries.
2. Insert the black test lead into the negative input jack and insert the red test
lead into positive input jack.
3. Touch the tip of the black test probe to the negative terminal and touch the
tip of the red test probe to the positive terminal of the battery under test.
4. The display will indicate BAD or GOOD.
