Hi All,
I have a project to do which is a Digital Multimeter.
It must be capable of measuring Voltage, Current and Resistance.
It must also feature a 3 1/2 digit display.

I have been thinkin about basing it around the 7106 IC.

My problem is that i am totally lost.
I would be greatful if anyone had or could point me in the right direction of some basic schematics.
Any other help or info would be greatful.

Kind Regards

 

We have a project on making a multimeter - http://www.allaboutcircuits.com/vol_6/chpt_3/11.html.

That should give you a start.

Hi Guys, Thanx for the help. Its been great.

If ya think of anymore please drop a message here for me,

Thanks Again

 

The complete schematic for making a digital voltmeter is in the datasheet of the ICL7106.
Then use Ohm's Law to let it measure current and resistance.

 

Hi again, posted a different thread by a mistake. Im looking for help with ISIS and ARES now.
Does anyone have a DMM circuit done out in ISIS or ARES?
I cannot find a suitable display in the ISIS library.

Thanks Again

 

Hi Guys. Could anyone help me out with the link that BEENTHERE has left me.
I am having problems trying to replicate the schematic for the kit in ISIS.
I am totally lost.
Could anyone be of assistance?

Kind Regards
