Select one of the following options:
l
Voltage:
Voltage excitation. A voltage is applied between the bridge
connection marked A (positive) and the bridge connection marked D
(negative). To set the voltage level either:
l
Enter the required voltage in the
Excitation span
column of the
spreadsheet style matrix.
l
In the simplified graphical diagram, use the
Excitation
box (
H
in
Figure 12.39 on page 257) to enter a value.
l
Voltage Sense:
Voltage excitation with sense. Sense inputs are used to
monitor the voltage at the sensor connection point. This puts the switch
marked S1a and S1b in Figure 12.39 on page 257 into the sense position.
Use the
Voltage
procedure to set the required voltage. The sense check
boxed (marked
E
in Figure 12.39 on page 257) can also be used to toggle
the sense lines.
l
Current:
Current excitation. A constant current is fed into the bridge. To
set the current level, do one of the following:
l
Enter the required current in the
Excitation current
column of the
spreadsheet style matrix.
l
In the simplified graphical diagram, use the
Excitation
box (
H
in
Figure 12.39 on page 257) to enter a value.
