„ Touch the test lead probes to the component under test, if the component is installed in a circuit, it is
best to disconnect one side before testing to eliminate interference with other devices.
„ Read the resistance in on the LCD display.
4.5. DIODE TEST
WARNING: Never test resistance on a live circuit.
„ Set the rotary function switch to the
„ Press the MODE button until the
„ Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana
plug into the + terminal.
„ Touch the test lead probes to the diode under test.
„ Forward voltage will indicate 0.4 to 0.7V on the LCD display; Reverse voltage will indicate OL; Shorted
devices will indicate near 0 and an open device will indicate OL in both polarities.
4.6. CONTINUITY CHECK
WARNING: Never test continuity on a live circuit.
„ Set the rotary function switch to the
„ Press the MODE button until the
„ Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana
plug into the + terminal.
„ Touch the test lead probes to the device or wire under test.
„ A beeper will sound if the resistance is approx. 50 Ω or less and the resistance reading will be shown
on the LCD display.
4.7. CAPACITANCE MEASUREMENT
WARNING: To avoid electric shock, disconnect power, remove the batteries and unplug the line cords
of the unit under test. Discharge all capacitors before taking any capacitance measurements.
„ Set the rotary function switch to the
„ Press the MODE button until the nF symbol appears on the LCD display.
„ Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana
plug into the + terminal.
„ Touch the test leads to the capacitor to be tested. Wait until the readings settle before ending the test.
„ Read the capacitance value in the display.
4.8. TEMPERATURE MEASUREMENT
WARNING: Do not touch the temperature probe to live circuits.
„ Set the function switch to the Temp position.
„ Press the MODE button to indicate °C or °F.
„ Connect the temperature probe to the banana plug adapter, note the - and + markings on the adapter.
„ Connect the adapter to the meter, making sure the - side goes into the COM terminal and the positive
side goes into the + terminal.
„ Touch the tip of the temperature probe to the object being measured.
„ Read the temperature on the LCD display.
4.9. NON-CONTACT AC VOLTAGE DETECTION
WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit
to verify proper operation.
„ Set the rotary function switch to the NCV position.
„ Hold the detector close to the AC voltage being tested.
