CAUTION: If the resister to be measured is connected to a circuit, to avoid damage to the
meter or to the equipment under test, disconnect circuit power and discharge all
capacitors before measuring resistance.
When measuring resistance at 200Ω range, the wires of test leads will add 0.1 Ω ~ 0.3 Ω of
measurement error. To achieve accurate measurement, you may reduce the reading by the
resistance of the leads. To test the leads, touch the probe tips together and read the
resistance of the leads.
When the resistance to be measured was above 1MΩ, it would take several seconds for
the meter to get a stable reading. This is a normal phenomenon.
Diode measurement
1. Connect the red test lead to the
“VΩmA”
jack and the black test lead to the
“COM”
jack.
2. Set the range switch to the desired diode range ( ).
3. 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.
4. Read the value on the LCD display.
Measure diode
CAUTION: If the diode to be measured is connected to a circuit, to avoid damage to the
meter or to the equipment under test, disconnect circuit power and discharge all
capacitors before measuring diodes.
You could use the diode range to test the voltage drop of diodes or other semiconductor
junction. A typical junction has forward voltage drop from 0.5V to 0.8V. If the connection
is reversed (open circuit), only figure “1” will be displayed on the LCD.
