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 function switch to the position.
2. Insert the black test lead into the negative COM terminal and
the red test lead into the positive terminal.
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
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 test lead into the negative COM terminal and
the red test lead into the positive terminal.
3. Press the MODE button to indicate  on 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 150, the audible
signal will sound. If the circuit is open, the display will indicate
“OL”.
DIODE TEST
1. Set the function switch to the position.
2. Press the MODE button to Touch the test probes to the diode
indicate on the display. under test. Forward voltage will
typically indicate 0.400 to 0.700V. Reverse voltage will indicate
