If it is desired to have both the input pins connected during calibration or test, the following connections
must be made. The positive test signal must be tied to SRB2 pin and the negative test signal must tie to
BIASIN pin. The channel multiplexer must be set for 111 and the SRB2 switch must be closed. This
multiplexer setting is illustrated in
