NOTE:
• In a circuit, a good diode should produce a forward bias reading of
voltage, however, the reverse-bias reading can be variable based on
resistance of other pathways between the probe tips.
• To avoid electric shock, never measure continuity on circuits of wires
with voltage.
RESISTANCE MEASUREMENT
WARNING:
To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any resistance measurements.
Remove the batteries and unplug the line cords.
1. Set the rotary switch to the desired resistance range.
2. Insert the black test lead banana plug into the negative COM jack,
insert the red test lead banana plug into the positive V jack.
3. Touch the test probe tips across the circuit or part under test. It is best
to disconnect one side of the part under test so the rest of the circuit
will not interfere with the resistance reading.
4. Read the resistance in the LCD display.
NOTE:
• The measured value of a resistor in a circuit usually is different from the
rated value of resistor, it is because the test current of the meter ows
through all possible paths between the probe tips.
• In order to ensure the best accuracy in measurement of low resistance,
short the test leads before the measurement and subtract this resistance
value of the test leads.
• For high resistance measurement, the meter may take a few seconds to
stabilize.
• In the open circuit, the meter display OL to indicate the over range.
CAPACITANCE MEASUREMENT
WARNING:
To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any capacitance measurements.
1. Set the rotary switch to desired capacitance range.
2. Insert the black test lead banana plug into the negative COM jack,
insert the red test lead banana plug into the positive mA CX jack.
3. Touch the test leads to the capacitor to be tested and read the
capacitance value in the display.
