5.5.13 Pro-AIn-F-4/12 Rev. A
Analog input module Pro-AIn-F-4/12 Rev. A with 4 ADC (12 bit) and 4 differen-
tial inputs.
The inputs are equipped with shielded LEMO sockets (CAMAC European
norm).
For the accurate adjustment of offset and gain the potentiometers Ox and Gx
are available (
fig. 116 ); you find information about the accurate adjustment on
page 68 . The "x" of the potentiometer’s names are place holders for the num-
ber of the corresponding ADC. The potentiometer names are imprinted on the
board.
