Almost all of these cheap meters are based on the ICL7106 chip; for a typical circuit see...

Quality varies greatly, I have had some with no fuse and no trimmer for calibration!

I was going to come in here to gawp at how terrible the multimeter was but then I realised I've seen this before sold in Maplins in the UK.  I only remember it because they were selling them instore buy one get one free.
I mean who would need one of these crappy meters, let alone two!

By the way ,2 years ago (or more) Fry's Electronics had in the paper selling an analog multimeter with mail in rebate for the same price. So the cost of the meter was the tax. I played with it for a while and with simple 9volt battery on different range and pop went the fuse :'(

So I think that would be the bottom of the cheap multimeter.
