I'm a hobbyist/diyer and have a cheap multimeter, currently one of these:
http://www.maplin.co.uk/Module.aspx?ModuleNo=44679
When new, I beleive it was accurate but now a new alkaline 1.5v battery shows 1.585 volts. I assume it should be 1.500 ?! Not great when you have a spent battery and it still shows just under 1.5.
Is this just what happens with cheap meters?
Secondly, there is a one potentiometer inside the unit. Is it likely that adjusting this will allow me to calibrate and is a good way to adjust it to get 1.5v from a new battery?
