COM
terminal on the back of the oscilloscope and
the red test lead to the
V/Ω/C
terminal.
(3)
Connect the red test lead to the positive terminal (anode) of the diode and the black
test lead to the negative terminal (cathode). The cathode of a diode is indicated with a
band. Read the diode forward bias.
Testing for Continuity

.
(2)
Connect the black test lead to the
COM
terminal on the back of the oscilloscope and
the red test lead to the
V/Ω/C
terminal.
(3)
Probe the test points to measure the resistance in the circuit. If the reading is below 50
, the multimeter will beep.
Measuring Capacitance
(1)
Push
DMM
button on the front panel. Select
in the bottom menu, select it until
switching to
C
.
(2)
Insert the supplied capacitance measurer to the
COM
terminal and the
V/Ω/C
terminal on the back of the oscilloscope.
(3)
Insert the capacitance to the capacitance measurer, then screen shows the capacitance
reading.
Note: when measuring the capacitance which is less than 5 nF, please use relative value
measuring mode to improve measuring precision.
