Diode & Continuity Test
1. Insert the black test lead into the “COM” jack and the red test
lead into the “ VΩmA ”
jack. At this time, the polarity of red test lead is “+”.
2. Set the function range switch to position, connect the red
test lead to the anode of the diode under test and the black test lead
to the cathode of the diode, and read the approximate forward
voltage drop value of the tested diode on the display.
3. Connect the test leads in parallel to two points of the circuit under
test. If the resistance between these two points is lower than about
50Ω, the built-in beeper will sound to indicate that the two points are
conducting.
4. The instrument will recognize diode and continuity test automati-
cally without switching the function knob.
Capacitance Test
In order to avoid damage to the meter or the equipment under
test, before measuring the capacitance, you should cut off all the
power of circuit under test and have all high voltage capacitors fully
discharged. Use DC voltage range to make sure that the capacitors
have been discharged.
Do not measure any voltage higher than 250V DC/AC RMS to
prevent electric shock or damage to the meter.
