10.4 RESISTANCE MEASUREMENT
Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
Set the rotary switch in the desired "Ω" position.
1.
Connect the red test lead to the "VmA" jack and the black test lead to
2.
the "COM" jack.
3. Connect the test leads to the resistor to be measured and read the
LCD display.
Notes

If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.

An over-range is indicated by 1 or -1. Set to a higher range.
10.5 DIODE AND CONTINUITY TEST
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
Set the rotary switch in the "
1.
mode. Set the rotary switch in the " " position for the continuity
measurement mode.
Connect the red test lead to the "VmA" jack and the black lead to the
2.
"COM" jack.
3. For measuring the diode, connect the red test lead to the anode of the
diode to be tested and the black test lead to the cathode of the diode.
The approx. forward voltage drop of the diode will be displayed.
For measuring continuity, connect the test leads to two points of the
circuit to be tested. If continuity exists, the built-in buzzer will sound.
10.6 NON-CONTACT AC VOLTAGE DETECTION
Even without buzzing sound, voltage may still be present. Do not
rely solely on non-contact voltage detection.
Set the rotary switch in the "NCV" position.
1.
2. Hold the meter close to the conductor to be measured. The buzzer will
sound when live voltage ≥ 90 V AC rms.
