2. Press the MODE button once to select
frequency. The “Hz” symbol will appear
on the display. To select Duty Cycle,
press the MODE button a second time.
The “%” symbol will appear on the display.
3. Insert the black test lead into the COM input jack
and the red test lead into the V input jack.
4. Touch the test lead probes to the circuit under test.
5. Read the frequency or % duty cycle on the LCD display.
6. Pressing the MODE button a third time will return the
meter to the voltage function.

1. Insert the black test lead into the COM
input jack.
2. For current measurements up to 10A AC/DC,
set the rotary function switch to the 10A
position and insert the red test lead into
the 10A input jack.
3. For current measurements up to 400mA
AC/DC, set the rotary function switch to
the mA position and insert the red test
lead into the mA input jack.
4. For current measurements up to 4000µA
AC/DC, set the rotary function switch to
the µA position and insert the red test lead
into the mA input jack.
5. Press the MODE button to select AC or
DC current. The “AC” or “DC” symbol
will appear on the LCD display.
6. Remove power from the circuit under test,
then open up the circuit at the point where
you wish to measure current.
7. Touch the test lead probes in series with
the circuit being measured. For DC current,
touch the red probe to the positive side of
the circuit and touch the black probe to the
negative side of the circuit.
8. Apply power to the circuit.
9. Read the current on the LCD display.
AC/DC Current Measurements
Observe all safety precautions when
working on live circuits. Do not measure current on circuits
that exceed 600V. Measurements in the 10A range should
be limited to 30 seconds every 15minutes.
