!! IMPORTANT !!
If one wants to use 4 wires in the CELL 1 terminal board or in the C1 connector (without using the SENSE signal),
one should short-circuiting - SEN with -EXC and +SEN with +EXC by closing the J1 and J2 jumpers.

•
SENSE JUMPER
J1 and J2 = if closed, REF and POWER , REFERENCE – and POWER SUPPLY – for the
channel 1 are jumpered on the board.
•
CALIBRATION JUMPER
CAL = if closed, it enables the access to the metrological parameters
•
I/O BOOT
Connector for the connection of the ALIBI MEMORY board or for the CLOCK board.
