4.13 Resistance Test
1) Insert black probe to COM jack, insert red probe to
INPUT jack.
2) Place measuring range switch to Ω position. At this
time, the meter is in the measurement state.
3) Connect the probe to the both ends of resistor or
circuit to be tested.
4) LCD will show readings.
Note:
1) When the input end is open, LCD shows “0L”
out-of-range state.
2) When the resistance to be tested > 1MΩ, the meter
reading will be stable after a few seconds, which is
normal for high resistance readings.
4.14 Diode Test
1) Insert black probe to COM jack, insert red probe to
INPUT jack.
2) Measuring switch is placed to position Ω .
3) Press “FUNC” key to switch to measuring state.
4) Connect the red probe to diode anode and connect the
black probe to diode cathode.
5) Read on the LCD.
Note:
1) What the meter shows is approximation of diode
forward voltage drop.
2) If the probe has reverse connection or the probe is
open, the LCD will show “0L”.
4.15 Circuit Continuity Test
1) Insert black probe to COM jack, insert red probe to
INPUT jack.
2) Measuring switch is placed to positionΩ .
3) Press “FUNC” key to switch to circuit continuity
measuring state.
4) Connect the probe to the both ends of circuit to be
tested .
5) If the resistance of circuit to be measured is less than
30Ω, the meter's built-in buzzer may sound.
6) Read the circuit resistance value on the LCD.
Note:
If the probe is open or circuits resistance to be tested is
more than 600Ω, the display will show “0L”.
4.16 Capacitance Measurement
1) Insert black probe to COM jack, insert red probe to
INPUT jack.
2) Rotary switch is placed to position .
3) After discharging capacitance completely, connect
the probe to the both ends of capacitor to be tested.
4) Read the capacitance on the LCD.
4.17 Surge Current Measurement
1) Place rotary switch to position A, press FUNC key to
switch AC current measurement state.
2) Press “INRUSH” key to enter surge current
measurement mode, at this time, LCD shows “- - - -”
3) Hold the trigger, open clamp head, clip one lead of
measurement circuit to be tested in the clamp.
4) When the meter detects surge current activation, the
meter will show and keep surge current value.
5) Read the current value on the LCD display.

Note:
1) Clamping two or more leads of circuit to be tested
simultaneously will not give correct readings.
2) To get accurate reading, connect the lead to be tested
at the center of current clamp.
3) In the manual measuring range mode, when LCD only
shows “OL”, which indicates over-range, choose
higher measuring range.
4) In the manual measuring range mode, if you don't
know the size of value to be measured in advance,
choose the highest measuring range, then decrease
gradually until the correct range is displayed..
4.18 NCV Measurement
1) Turn t he mete r to NCV gr ade.
2) The met er show s “NCV” s ign, th e ma in disp lay of
