Electronic – What Ways to Calibrate a Multimeter


How can one calibrate a multimeter, like a UT61E or any other multimeter in the 50 ~200 $ pricemark, when one does NOT have an expensive FLUKE nor a friend who has a FLUKE)

Best Answer

Very generally and at the most basic, you need a precision voltage reference and resistors. Obtaining 0.1% is fairly easy, for resistors it's straightforward, and for voltage references look up "precision voltage reference" (something like this), and bias it with 0.1 to 1 mA.

The actual calibration procedure will vary from meter to meter, so you will need to dig up the appropriate documents.
