Voltage: Voltage excitation. When you select voltage excitation a voltage
l
is applied between the bridge connection marked A (plus) and the bridge
connection marked D (minus). To set the voltage level do one of the
following:
In the spreadsheet style matrix in the Excitation span column enter
l
the required voltage.
In the simplified graphical diagram use the Excitation box (H in Figure
l
12.17 on page 273) to enter a value.
Voltage Sense: Voltage excitation with sense. When you select this option
l
the sense lines are used: this will put the switch marked S1a and S1b in
Figure 12.17 on page 273 into the sense position. Use the Voltage
procedure to set the required voltage. You can also use the sense check
boxes (marked E in Figure 12.17 on page 273) to toggle the sense lines.
Current: Current excitation. Now a constant current is fed into the bridge.
