4. Configure the excitation level.
You can select the level of excitation applied to each excitation
channel, again using two jumpers per channel—W16, W24, W25,
W26, W36, W37, W48, and W49. If you select voltage mode, you can
apply a potential difference of either 3.333 V or 10.00 V. If you select
current mode, you can apply an excitation current of either 0.150 mA
or 0.450 mA. Refer to the transducer specifications to determine the
necessary excitation level. See Table 3-13 for the SCXI-1121
excitation level jumper settings, and refer to Table 3-14 for the
maximum load per excitation channel.
