test for diamond using diamond & moissanite tester
analog meter - need advice on reading the dc voltage scale?
i am havinga problem understanding how some reading on an analog
tester is arrived at.On the face of an analog meter the dc v is marked from 0-10vdc,0-50 vdcand 0-250 vdc.
I am now looking on a meter as i write and the pointer shows 7.25dc v on the 0-10 scale,37.5dc v on the 0-50dc v scale and 185 dc v on the 0-250 scale.According to the book i am reading from,it said the pointer reads about 80 vdc and if the range selector is set at 2.5vdc then the measurement voltage value would be 0.80 vdc
I just do not understand how the author arrive at the 80 or the 0.80 vdc!!
When you set the range, that determines which scale to read.
So if you selected 2.5vdc, you would read the 0-250 scale.
It's the only one which exactly matches your range selection.
You have to assume a decimal point, 2 places from the right.
So if the needle reads 80, then it should be interpreted as 0.80vdc.
