Option 0
Use this option to exit the program.
Option 1
Use this option to read the shunt tolerance, the last measured shunt values, the
reference values, and the shunt error status.
Note
The shunt error status is not maintained over power cycles, so it is only
valid if the shunt is executed after power is applied. Refer to
This option asks if you want to save the data in a file. Answer Y or N, and if Y,
then supply the file name when prompted. The following is typical of what is
displayed when this selection is made:
Note
If you save to a file, the file is created in the same directory as the tishunt
program. The file name must contain less than 80 characters.
Option 2
Use this to set the shunt tolerance. When selected, the following is displayed:

The Shunt Tolerance specifies how much the measured shunt deltas may
deviate from the Ref settings, and still be considered good.
The value is entered as a percentage, where "1.0" would mean 1.0% of the
Ref settings.
For example: if the tolerance is 1%, and the Ref setting is 8.0, then the
measured delta must be between 7.92 and 8.08 to be considered good.
It is not necessary to reboot the TI when this value is changed, but a
Shunt Calibration must be executed to update the Shunt Error Status
words.
Also note that a parameter download will overwrite this value.
