DIODE TEST & CONTINUITY MEASUREMENT
To avoid electric shock, never measure continuity on circuits or wires that
have voltage on them.
1) Insert the black test lead banana plug in tothe negative COM input
jack.
2) Insert the red test lead banana plug into the positive V input jack.
3) Turn the function switch to the position.
4) To perform the diode test, press the mode button until appears on
the screen.
5) Touch the test probes to the diode under test. Forward voltage will
indicate 0.4V to 0.7V. Reverse voltage will indicate OL. Shorted devices
will display 0mV and an Open device will indicate OL in both polarities.
6) To measure continuity, press the mode button until appears on the
screen.
7) Touch the test probe tips to the circuit or wire you wish to test. If
the resistance is less than approximately 150Ω, an audible signal will
sound. If the circuit is open, the display will indicate OL.
RESISTANCE MEASUREMENT
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) Insert the black test lead banana plug into the negative COM input
jack.
2) Insert the red test lead banana plug into the positive V input jack.
3) Turn the function switch to the Ω position.
4) Touch the test probe tips across the circuit or component under test
so that the rest of the circuit will not interfere with the resistance
reading.
5) For resistance tests, read the resistance on the LCD display.
