Resistance Measurement
1.
Insert the black test lead into the negative
(COM)
terminal and the red test lead into the
positive
(V/Ω/Temp)
terminal.
2.
Set the function switch to the
"Ω
CAP
"
position.
3.
Touch the test probe tips across the circuit or component under test. It is best to
disconnect one side of the device under test so the rest of the circuit will not interfere with
the resistance reading.
4.
For resistance test, read the resistance on the LCD display.
Diode and Continuity Test
1.
Insert the black test lead banana plug into the negative
(COM)
jack and the red test lead
banana plug into the positive diode jack.
2.
Turn the rotary switch to the
"Ω
CAP
"
position.
3.
Press the
ʺMODEʺ
button until
symbol appears on the display.
4.
Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V.
Reverse voltage will indicate
ʺOLʺ
. Shorted devices will indicate near 0 mV and an
open device will indicate
ʺOLʺ
in both polarities.
For continuity test: if the resistance is <150
, a tone will sound.
