When receiving input from a conventional 4-arm strain gage bridge, a 10A72-2C chan-
nel should remain in the factory-set “TRANSDUCER” mode. When conditioning input
from a 1/4-bridge (1-arm) or 1/2-bridge (2-arm) strain gage configuration, however,
the channel should be set to “GAGE” mode, as follows:*
1.
Remove the 10A72-2C card from its mainframe slot. For “Card Insertion and
Removal,” see Manual Section 1.B. Since the 10A72-2C is “hot-pluggable,” you
need NOT turn off mainframe power before removing the card.
2.
Refer to Fig. 3 and locate the CONDITIONER MODE PROGRAMMING JUMPER
PINS for Channels 1 and 2. One “minijumper” is provided for each channel, for
interconnecting adjacent jumper pins.
3.
Position the jumper for each channel as shown in Fig. 3 to set the desired mode
for that channel.
4.
Keep out the 10A72-2C card for the excitation selection procedure, below.

To set the DC excitation for each 10A72-2C channel, you should
1.
Refer to Fig. 3 and locate the EXCITATION VOLTAGE PROGRAMMING JUMPER
PINS for Channels 1 and 2. One “minijumper” is provided for each channel, for
interconnecting adjacent jumper pins.
2.
Position the jumper for each channel as shown in Fig. 3 to set the desired excita-
tion for that channel (1, 5, or 10 V).
3.
Keep out the 10A72-2C card for the filter selection procedure, below.

* In “GAGE” mode, the 10A72-2C requires the connection of a
Model 10CJB-2 Dual Bridge
Completion Card
, or equivalent circuitry provided by the user (see Section 4). The purpose
of the “GAGE” setting is to ensure compatibility with special applications of the older Model
10A72-2 where it was not required that the “CAL SENSE” line be tied to the “+ SIGNAL” line.
