INSTRUCTIONS To Mr Clark. 5/8/19 Order No. ____ Customer's No. ____ 225 volts every time | Condenser | Packing | Reading | diff | Cap. | |---|---|---|---|---| | A | .0166 | .0271 | .0105 | .180 | | B | .0166 | .0256 | .009 | .155 | | C | .0166 | .0300 | .0134 | .230 | The above are the three condensers in cases & complete ready for fitting to Cars. 225 volts gives .0166 amp. Susceptance = .0166 / 225 = 73.8 micromhos K = 73.8 / 262 = .281 m f Constant for multiplying readings = .281 / .0166 = 17.0 approx.
