The 16 channels are divided into two banks. The banks are combined
by closing K327 for voltage and 2-wire Ohms switching. When K327
is open, the banks are electrically independent of each other and this
configuration is used for 4-wire Ohms multiplexing where the Ohms
current source is connected to channels 1 through 8 and the sense is
obtained from channels 9 through 16. Relays K326 and K328 control
the connection to the analog bus for measurements using the
internal DMM.
