Operation instruction
Measuring voltage
1) Set the function switch to V
range. The LCD displays "AUTO AC" or
"AUTO DC".
2) Connect the test leads across the source
or load to be measured.
3) Read the LCD display. The polarity of the
RED lead connection will be indicated
when making a DC measurement.
4) If the AC voltage is tested, the LCD shows
the value of the AC voltage.
5) Press the Hz% key to select the
measurement of frequency or duty cycle.
Note:
• Be careful to avoid electric shocks
when measuring high voltages.
After completing the measurement,
disconnect the meter lead from the
circuit being tested.
• Pure DC voltage does not have a
frequency or duty cycle, so the operation
is invalid for DC voltage tests.

Measure resistance
1) Set the range switch to
resistance test function is the meter's
default function.
2) Connect the test leads across the load to
be measured.
3) Read the reading on the display.
Note:
• In order to avoid damage to the
instrument when measuring the
resistance online, make sure that the
circuit under test is turned off . Also note
that capacitance can only be measured
once the electricity has been discharged.
• When measuring resistance in a 400Ω
range, the meter lead will cause a
measuring error of 0.1 g to 0.9. In order to
get the exact reading, you can subtract
the red and black reading values for the
� nal reading. It is recommended that the
function for measuring the relative value
of the instrument be used.
• When there is no input, such as in an
open circuit situation, the meter shows
"OL". When the measured resistance is
greater than MΩ, it takes several seconds
for the instrument to be able to read
steadily. This is perfectly normal.
Continuity test
1) Set the range switch to
2) Press the "SELECT. " key to select
continuity measurement mode. The
symbol " " will appear as an indicator.
3) Connect the test leads across the load to
be measured.
4) If the circuit resistance is lower than
about 60Ω, the built-in buzzer will sound.
