PINBAR

PIN BAR

• All values are including the measuring cables!
• Nomenclature:
  • Greek numbers = Filter Box on the top
  • Xi = Plug at the corresponding Filter Box (e.g. : VI, X3 = Plug X3 at Filter Box VI )
  • Xi:j = Pin j at Plug Xi (e.g. : VI, X3:4 = Pin 4 at Plug X3 at Filter Box VI )
  • R_1/2 = Resistance between Pin 1 and 2 directly measured at a corresponding PIN BAR
  • R_X3:1-2 = Resistance between Pin 1 and 2 measured at Plug X3 of the Filter Box.

MIXING CHAMBER

There are six PIN BARS (A-F) mounted on the mixing chamber. Each consits of 16 PINS arranged in two columns.
