I am looking for a calibration procedure for a Lincoln Thermal Converter, manufactured by Sangamo Electric of Springfield, Illinois.
Alternate associated names might include Leeds & Northrup, Scientific Columbus, Teledyne or Angus/Estherline.
I'm guessing these were built approx. 1963.
The "Type" is CW10, "Spec. no" is 55887, 60MV=2KW, 10AMPS, 120VOLTS, 2ELEMENTS, 3PHASE, 3WIRE.
I've spent a lot of time looking on the web but can't find a manual of any kind for these instruments. Any help would be appreciated. Thanks, Kevin.
