[Elecraft] K2/100 moron question from NZ7C

[Joe Montierth]

The ~ scale is for AC amps (~ signifies sine wave). Try the scale with three
solid bars, that should be DC. Make sure your test probes are in the right
holes on your DMM, many times they have to be moved to read amps. Usually
says something like 10A unfused. Go from that position to common.
