(2) Connect the black test lead to the COM terminal on the top 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

(1) Push DMM button on the front panel. Select
it until switching to
(2) Connect the black test lead to the COM terminal on the top 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
it until switching to C.
(2) Insert the supplied capacitance measurer to the COM terminal and the V/Ω/C
terminal on the top 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.

Multimeter Features

Data Hold Mode

You can freeze the display for any function.
(1) Select Hold in the bottom menu as ON.
(2) Select OFF to exit this mode.

Making Relative Measurements

When making relative measurements, reading is the difference between a stored
reference value and the input signal.
(1) Select Configure in the bottom menu, select Relative in the right menu to
enter the relative mode.
The measurement value at this time is stored as the reference value, and
displayed behind △.
In this mode, current reading = input value - reference value.
(2) Press it again to exit the mode.
Note: This function is not available when measuring resistance, diodes, and
