Diodetest - KPS DCM4000T Manuel D'instructions

DCM4000T
3) In HZ/DUTY Measurement Mode:
WARNING
Electric shock hazard.
Pay special attention to avoid shock when measuring high voltage.
Don't input voltage more than AC250 T-RMS.
1) Insert black probe to COM jack, insert red probe to INPUT jack.
2) Transfer switch is placed to position HZ/%.
3) Connect the probe with signal or both ends of load in parallel for measurement.
4) Read on the LCD.
5) Pressing the FUNC key again can enter duty ratio measuring state.
Note:
The range of Hz/% measure function can upper to 60kHz. When the frequency to be tested is
more than 10Hz,the LCD will show "00.0"measuring frequency higher than 10 kHz is possible, but
accuracy is not guarantee
4.13 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 "Ω". At this time, the meter is in the measurement state.
Use FUNC key to select the resistance measure.
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
4.14 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".
. Use FUNC key.
