Calibration Method:
1) Turn off the meter. Use 2 wires to shortcircuit the little metal sheet marked with 1, 2 and 3; don't release the shortcircuit wires until
step 3.
2) Push the start button to turn on the meter. The screen will show self test mode, the 2nd line will show ? Mark. Push the start button
again quickly and Calibration will start.
3) When screen shows T4 isolate Probe, remove the shortcircuit wires.
4) When screen shows 1-II-3 >100nf, connect a non-polar capacitor (>100nf) to the meter, the calibration procedure will keep going until
completion.
V Test examples
1.
It shows that no device is connected on test
terminals or an unknown part. It may also be that
the devise was damaged.
2. Test a resistor
It shows the DUT is an 195.6Ω resistor, between
terminal 1 and 2.
3. Test a diode
It shows that the DUT is a diode, test terminal 1 is
connected to cathode, and test terminal 2 is
connected to anode. The forward voltage is
1.91mV. Junction capacitance is 4pF.
4. Test a capacitor
It shows that the DUT between terminal 2 and 3 is a capacitor.
Capacitance =991.7uF, ESR=0.02 ohm and Voltage loss is
1.5%.
5. Test a triac
It shows that the DUT is a triac, test terminals 1, 2 and 3 are
connected to control gate G, anode A, Anode K.
6. Test a MOS FET
It shows that the DUT is PMOS FET, test terminals 1, 2 and 3
are connected to pin S, D and G. There is a protect diode
between S and D, the anode of the diode is connected to D,
and the cathode of the diode is connected to S.Junction
capacitance is 673pF; the gate threshold voltage is 3.05V.
