checking voltage
« on: June 06, 2015, 06:26:38 pm »
 You say. If in doubt check voltage. I understand that all meters are different so if a part in a circuit is supposed to be 4v at what
plus and minus point would you call it bad.
Thanks. Leo

  • There's more value if you figure it out yourself!

+/- 5% max, then start to ask why... unless the supply is marked as being better than 5%
Don't ask a question if you aren't willing to listen to the answer.

If you are concerned about the accuracy of your meter, then get one of the cheap 5v volt reference diodes like a LM4040 or one of the many similar devices to see how good it really is.
Some meters do have internal adjusters to you can recalibrate for that particular range.
