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.
