How to detect the quality of the PPR pipe thermal melt using the digital multimeter (without the temperature controller, one)

0 Comments

No temperature controller, no switch, not adjusting the temperature,

Without counting, no power board.

The hot melt is always bright green, no red light, the green light begins

Finally heating.

Dial the digital multimeter to 2K Ohm resistor, red and black table

The pens are exposed to the plug of the thermal melt line and the line of fire, respectively

There is no sound with a watch, the red indicator is not bright, the screen

Display resistance (in the state of view),

Then prove that the power cord and the heating board are good

of. If the multimeter display 1 or OL, for

Endless, then prove that the power cord or the heating board is

bad.

Dial the digital multimeter to 200 ohm resistance file, red

The black table pen exposes the two connections of the thermal board of the hot meltr

Line columns, universal watches without sound, red indicator

The lights are not on, and the universal screen screen displays resistance values

(In the state of view), that proves the fever of the hot melt

The board is good and can continue to be used.

Universal watch is still 200 ohm resistance file, red and black table pen points

Don’t contact the two ends of the zero line of the power cord, there is no multimeter watch

The sound, the red indicator is not on, the screen is blocked

Value, red and black table pens are connected to the fire line of the power line, respectively

Duan, there is no sound on the multimeter, the red indicator is not on,

The screen displays resistance (in the state of view),

Then prove that the power cord is good.

Dial the digital multimeter to the bee ring file (bee tweet gear and

The diodes are together), red and black tables are exposed to contact

Two wiring columns of the heating board, the universal watch continues to make a sound

The sound, the red indicator light is often on, the screen displays resistance value

(In the state of view), then it proves that the hot melt heating board

It is good, you can continue to use it.

Digital multimeter is still the bee ring file (bee tweet file and

At the two ends of the zero line of the power cord, the universal watch continues to make a sound

The red and black watch and pens are connected to the two ends of the fire line of the power cord,

The multimeter continues to make a sound, and the red indicator lights are often on,

The screen displays resistance (in the state of view), that certificate, that certificate

The Mingdian source line is good and can continue to be used.

Dial the digital multimeter to the bee tweet, red and black table pen points

Do not contact the zero line and fire of the power line, the universal meter continues to be sent

When the sound, the red indicator light is often on, and the screen is blocked

Value, then prove the power cord, green indicator light, heat

The boards are all good.

How to wiring inside?

There are 9 lines.

There are three lines of the power cord, and one is a blue line (zero

Line), one is a brown line (fire line), one

It is a yellow -green two -color line (ground line).

There are two green lines on the green indicator light,

There are two red lines of red indicator lights,

There are two red threads in the heating board.

The two red threads of the red indicator lamp are empty without connecting,

The ground line (yellow -green two -color) is empty without connecting.

Raising the heating board any red wire connection electric source line coffee brown

The line (fire line), any green of the green indicator light

The color line, these three lines must be connected together.

The red wire connecting power line left on the heating board is blue

Line (zero line), green indicator light left

The diodes are together), red and black tables are exposed to contact

The sound, the red indicator light is often on, the screen displays resistance value

The color line, these three lines must be connected together.
