Specifications

C-5 Measuring Resistance
1) Connect the black test lead to “COM” jack
and red test lead “Ω”jack.
2) Set rotary switch to “Ω”
3) Connect the test leads across with the object
to be measured.
Caution
1) If “1” is shown on the LCD, which means the
Meter is overloaded, then set a higher measuring
range. If resistance is above 1MΩ, the reading
will only be steady in few seconds which is
normal for measuring higher value of resistance
2) “1” is displayed when open circuit or no input.
3) Make sure all objects, circuit and components
to be measured are without voltage and
discharge all high-voltage capacitors.
C-6 Measuring Capacitance
1) Input the being measured capacitor to the
capacitance jack (not require test lead)
2) Before measuring capacitance, remember it
takes time for zeroing when changing ranges.
Floating reading does not effect accuracy.
Caution
1) To avoid damage of the Meter or the equipment
under test, disconnect circuit powers and
discharge all high-voltage capacitors before
measuring capacitance.
2) Input capacitor to the capacitance jack.
3) Stabilizing reading takes time when measuring
high capacitance
4) Unit: 1pF=10 µF, 1nF = 10 µF
