Turn off the circuit to be tested. The black test
probe is connected to one end of disconnected
circuit (low voltage relatively), and the red test
probe is connected to the other end of disconnected
circuit (high voltage relatively). (When measuring
direct current, connecting test probe reversely
would make reading become negative, but the
meter won't be damaged.)
Connect the power to the circuit, then read the
display reading. If it is overload, “OL” will display
on the LCD display.

To prevent injury or damage to meter and
equipment, do not make current measurements
if voltage exceeds 600V.
Note
Before measuring current, first check the meter's
fuse. When measuring, use correct input end and
function. When the test probe is inserted to the
current input end, don't connect the other end
of the test probe with any circuit in parallel
Warning
Resistance measurement:
Rotate function selection switch to resistance
measurement position, and turn off the power to
the circuit to be tested
If needed, press “FUNC” key to select resistance

Connect black and red test probe to COM input
jack and VΩmA input jack, respectively.
Measure the resistance of circuit to be tested with
other ends of test probes.
Read the resistance value from LCD display. If it
is overload, “OL” will display on the LCD display

Here are some tips for measuring resistance:
• The resistance measured on a circuit is usually
different from the rated value of resistance. This is
because the test current of the meter will flow through
all possible channels between test probes.
• When measuring low resistance, to ensure accuracy,
make a short circuit between the test probes and
read the resistance value of the short circuit. This
resistance value should be subtracted after measuring
the resistance to be tested.
• When there is no input (for example, open circuit),
the display will show “OL”, which means that the
measured value is out of range.
When measuring resistance or circuit continuity,
to avoid injury or meter damage, turn off the
power to the circuit and discharge all capacitors.
