Fig. 9(a) gives standard cabling for connecting to the Model 3560 Voltage Con-
ditioner a general ANALOG SIGNAL SOURCE, floating or grounded, with its own
power supply (if required); Fig. 9(b), for connecting an EXTERNAL ZERO-TO-FULL-
SCALE POTENTIOMETER with a resistance from 2 to 10 kilohms, using the instru-
ment's ±12-V excitation; and Fig. 9(c), for connecting an EXTERNAL DC-TO-DC
LVDT, again using the ±12-V excitation. As shown in Fig. 9(a), a floating input is to
be grounded by tying the transducer's –SIGNAL line to the SIG COM terminal.
When a –SIGNAL line from the transducer is not available, the –SIG and SIG COM
terminals should be connected by a jumper wire (as in Figs. 9(b) and 9(c)).
