#324: How to "calibrate" the Simpson 260 VOM - BONUS: 50 microamp current source
This video describes the function of each calibration adjustment on the Simpson 260 volt-ohm-milliammeter. I also describe (at the end) a 50uA current source (using a Wilson current mirror) I put together to make the initial adjustments on the 260 easier. I don't show the 10A current shunt adjustment because I don't have a good 10A source to use. Please note that I am not a Metrology or Calibration professional, and don't have any traceable standards. The purpose here is to show what each adjustment does. My notes for this video are here: http://www.qsl.net/w2aew/youtube/Simp...
