Proteus simulation-Multimeter

[marius9612]

Hi, I have to do the drawings in the drawing in Proteus, but I do not succeed, I do not understand something. You can help me.Thanks.

Wow... A bit of a mess.... I doubt anyone can help on this information.. You are going to have to do the drawings in paint then explain some of your symbols... I don't recognise them..

Moved to homework help!!

 

[marius9612]

It should measure current and voltage in DC (voltage and current divider)

 

[Ian Rogers]

Here are the symbols I use

What is this??

 

[marius9612]

From what I remember it was a transistor, but he said we could use buttons more easily

Er! I think you have tried to copy the circuit from memory!
Is this what's required?

Yes it is, except that they are combined and I had 1/8, which does not appear in the drawing.
And there's the one above that would be something of a power divider, which I don't know how to do

 

[Ian Rogers]

6k and 1k doesn't make 1/8th...

Power divider? Do you mean regulator 20v -> 5v..

 

[marius9612]

no power divider,sorry.Current divider

Try again, voltage divider.

 

[marius9612]

Try again, voltage divider.

yes those that I did give them that is, but it is the one above in the first drawing, I was referring to it

 

[Ian Rogers]

Then the current in the "voltage divider" will differ from circuit to circuit... Hence so will the voltage... To get 5V from 20 and keep the same ratio's you'll need a regulator or at least a Zener!

Well it's impossible to tell anything from the first drawing, it's looks mostly like a spider has just crawled through a blob of ink

What a hurtful comment, spiders deserve our respect.

the first drawing signifies a part of a DC multimeter that measures current and voltage

from 5v to 20v is the measuring range

Setting 5 volts
