RESISTANCE MEASUREMENTS
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 function switch to the
position.
2.
Insert the black test lead banana plug into the negative (COM) jack
and the red test lead banana plug into the positive
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 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.
1.
Set the function switch to the position.
2.
Insert the black lead banana plug into the negative (-) jack (COM)
and the red test lead banana plug into the positive (+) jack (
).
3.
Press the button until the symbol appears in the display.
4.
Touch the test probe tips to the circuit or wire you wish to check.
5.
If the resistance is less than approximately 30
, the audible signal
