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 ).
- R1/2 = Resistance between Pin 1 and 2 directly measured at a corresponding PIN BAR.
- RX3:1-2 = Resistance between Pin 1 at Plug X3 of the Filter Box and Pin 2 at the PIN BAR.
- RX3:1/2 = Resistance between Pin 1 and Pin 2 at Plug X3 of the Filter Box.
MIXING CHAMBER
There are six PIN BARS (A-F) mounted on the mixing chamber. Each consists of 16 PINS arranged in two columns.
