RESISTANCE [
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.
6. Set the function switch to the Ω position.
7. Insert the black test lead plug into the negative (COM) socket and the red test lead
plug into the positive Ω jack.
8. Press the MODE button until "Ω" appears in the display.
9. 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.
10. Read the resistance in the display. The display will indicate the proper decimal
point, value and symbol.
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits or wires that have
voltage on them.
