4. Touch the test probe tips to the circuit or wire you wish
to check.
5. If the resistance is less than
approximately 35 , the audible
signal will sound. If the circuit is
open, the display will indicate
“OL”.
DIODE TEST
1. Set the function switch to the Ω
position.
2. Insert the black test lead
banana plug into the
negative COM jack and
the red test lead banana
plug into the positive V
jack.
3. Press the MODE button to indicate “ “ and “V” on the
display.
4. Touch the test probes to the diode under test. Forward
voltage will typically indicate 0.400 to 0.700V. Reverse
voltage will indicate “OL”. Shorted devices will indicate near
0V and an open device will indicate “OL” in both polarities.
CAPACITANCE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect power to the
unit under test and discharge all
capacitors before taking any
capacitance measurements. Remove the batteries and
unplug the line cords.
1. Set the rotary function switch to the CAP position.
2. Insert the black test lead
banana plug into the
