Hey guys look at pictures in mark area. Is this zener diode ??

 

I don't know what it is but my guess is a thermistor.
What is the board part of?

 

It could be a surface mount Red LED, what is value of the resistor inline with it, covered by your red line.?

 

If I were to guess at this, going from the second image, it looks like it is non-populated and there is a blob of adhesive on the PCB.

 

I'm with Mickster. It's a blob of glue.

I think you're right. I thought I could see connections to the solder pads but having looked again I don't think there any.

 

The pcb markings says C81, so it would be a capacitor if it was fitted.

 

Hey guys look every resistor middle that part present on.
That pcb from LED light.

LED light bulbs

 

The adhesive is there to stop the components from falling off or shifting during soldering.
To be more specific, falling off refers to when the components are on the bottom side during a wave soldering process.

 

I receive some values in this part. Zener diode and this part values are same. So i
Would consider as a zener diode

 

Finally i find out

 

You will get similar readings from any silicon diode except schottky so you still don't know what kind of diode it is, let alone what voltage and current ratings are necessary.

Yah, i am going to find out.
You look at the pictures it is orange colour like zener diode. So i decide it. But within two days i will show whole thing in pcb and its ratings

 

This is a 1N4148 small signal diode:

 

I'm using this diode 1N4148 and get result.

 

Your multi-meter probes are connected to pads for a non-populated device.
The only reason your meter is showing a value, is because the test current is going through other devices in the circuit and giving you a false reading, for what you think is there but is not.
Please post a clear, high resolution photo of the complete circuit and you will get some guidance as to why you are getting this.

 

its not a zener, its just pcb glue for mounted surface components, you can google it
