sockets for each channel as desired (see figures).
In voltage mode, RA and RB (installed by the user) form a resistor divider network. In current mode, RA is
always shorted, RB is shunted with a resistor. 8 channels can be configured alike with 16-pin, 8-resistor DIP-8
resistor networks. With no resistors, DBK15 provides 16 differential voltage inputs for +5 V full-scale inputs.
CL positions are used for bias resistors if necessary. Two differential measurement configurations can be used:
floating or referenced differential. Refer to the Signal Management chapter for more information.
