Reading an analog meter

  1. Sep 20, 2006 #1
    Sorry, this sounds like a silly but I grew up in the age of auto-ranging multimeters.

    Say you have a scale, 1 to 10 and you select your scale as 1 miliamp. I presume if the needle is at 7 then that means 7 miliamps and NOT (7/10) 0.7 miliamps?

    No, it means .7 milliamps. The range is the top of the scale.

    Oh, I guess it's not like an oscilloscope when you set it to say .5 V/div and just mulitply the number of divisions to get the voltage. Silly me.
