Note:
• If the resistance reading is greater than 0.5
when the test leads are shorted (connected to
each other), check if the test leads are loose or
damaged.
• The display will show “
” if there is an open
circuit for the tested resistor or if the resistor
value is higher than the maximum resistance
range of the multimeter.
• When measuring low resistance, the resistance
of the test leads may affect the test result,
causing a 0.1
Ω

Ω
measurement error. To
get an accurate measurement, first test the
resistance of the test leads by connecting them
to each other, and subtract this value from the
final measurement result.
• When testing high-resistance objects, it is
normal to wait for several seconds to obtain a
stable reading (>1M
Ω
).

WARNING
Before measuring, switch off the power
supply of the circuit, and fully discharge
all capacitors.

3. Connect the test leads in parallel to the
object being measured. Hold them in place
until the reading on the display stabilizes.
