SIGNAL INPUT, module ME
OVERVIEW
This module together with the "MP" input board, performs all the input signal conditioning (see Fig. 2). This module contains the trimmers and jumpers for the amplifier gain and the low level output (offset).
The signal input connections are made at Terminals 3, 4, 5 and 6.
Each model may use some of these terminals, see the Connections Section.
