4.11 Resistance Test
WARNING
Electric shock hazard.
When measuring circuit impedance, determine that the power supply is disconnected and the
capacitor in the circuit is completely discharged.
1) Insert black probe to COM jack, insert red probe to INPUT jack.
2) Place measuring range switch to position "
3) Connect the probe to the both ends of resistor or circuit to be tested for measurement.
4) LCD will show readings.
Note:
1) When the input end is open, LCD shows "OL" outrange state. .
2) When the resistance to be tested > 1M, the meter reading will stabilize after a few seconds, which
is normal for high resistance readings
4.12 Diode Test
1) Insert black probe to COM Jack, insert red probe to INPUT Jack
2) Measuring switch is placed to position
3) Connect the red probe to diode anode and connect the black probe to diode cathode to make
test.
4) 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 "OL".
4.13 Circuit Continuty Test
WARNING
Electric shock hazard.
When measuring circuit continuity, determine that the power supply is disconnected and the
capacitor in the circuit is completely discharges.
1) Insert black probe to COM Jack, insert the red probe to INPUT Jack
2) Measuring switch is placed to position
3) Connect the probe to the both ends of circuit to be tested for the Measurement
4) If the resistance of circuit under test is less than 50Ω, the meter´s built-in buzzer may sound.
5) Read the circuit resistance value on the LCD
. At this time, the meter is in the measurement state.
