2.1. Function and role of test gear
Power switch: On or off the power supply of digital multimeter.
Data holding switch: Memorize the measured data, which is convenient for comparing
the measured data.
Peak sounding: Measure diode quality, line on-off, alarm function.
Resistance file: Measure the quality and value of resistance.
DC Voltage Range: Measure DC Voltage.
AC Voltage Range: Measure AC Voltage.
V Ω/COM: Red Pen Port (+ Pole) in V Ω Test and Black Pen Port (-Pole) in COM Test
Note: When carrying out resistance or voltage test, we should choose the appropriate
measuring range. If the measuring range is too small, it will not be measured. If the
measuring range is too small, it will be too large
Large test error range; When the measuring voltage is unknown, choose a larger range
for measurement.

2.2. Line on/off measurement
As shown in the left figure, first hit the multimeter to the
buzzer file and turn on its power switch. At this time, the
multimeter displays "1."; Then the two probes are
distributed and contacted with the metal thread ends at
both ends of the red wire in the figure. At this time, the
multimeter still shows "1." There is no change, which
means that there is an open circuit in the middle of the
wire, that is, the line is impassable.
As shown in the left figure, test with the same method
as described above. If the multimeter displays the
number ". 003" or ". 00N" and sounds an alarm, it
means that the wire is conductive.
Open circuit
Conduction

2.3. Measurement of motor
Motor
measur
ement
As shown in the left figure,
it is shown as "1",
indicating that the internal
coil of the motor has been
open and poor.
As shown in the left figure,
the result is "42.5" Ω,
which is within the normal
resistance range,
indicating that the motor
is good.
--Other motor coil resistance reference
Air pump DC24V: 5-8 Ω solenoid valve DC24V: 157 Ω
Motor DC24V: 5-10 Ω Electric Cylinder DC24V: about 10 Ω

2.4. Measurement of AC Voltage
--As shown in the above figure: Measure the power supply of household plug-in board
(220V), select 700 measuring range, and the test result is "225", which means that the
actual voltage of this group of sockets is 225V at this moment (the switch is pressed
down, so there is electricity and the lamp is illuminated).
--As shown in the above figure: Measure the power supply of our household plug-
in board (220V), select 700, and the test result is "000", which means that the
actual voltage of this group of sockets is 0V at the moment (the switch is not
pressed, so there is no electricity and the lamp is not on).

2.5. Measurement of AC Voltage
Second, the introduction of common tools and parameters
-As shown in the above figure: the test result shows "1.58", which means that the
voltage at both ends of this battery is 1.58 V, and the red pen is connected to the "+"
pole of the battery, while the black pen is connected to the electromagnetic "-" pole.
-As shown in the above figure: the test result shows "-1.58", which means that the
voltage at both ends of this battery is 1.58 V, and the red pen is connected to the "-
" pole of the battery, while the black pen is connected to the electromagnetic "+"
pole.
