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
, “Shunt
Error Status,” on page 57.
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:
Reading Shunt parameters from TI... OK
Shunt Delta Tol: 10.000%
FX1 Ref: 3.935 Measured: 3.934 Error Status: 0
FX2 Ref: 3.932 Measured: 3.932 Error Status: 0
FY1 Ref: 3.937 Measured: 3.930 Error Status: 0
FY2 Ref: 3.929 Measured: 3.930 Error Status: 0
FY3 Ref: 3.932 Measured: 3.932 Error Status: 0
FY4 Ref: 3.931 Measured: 3.932 Error Status: 0
FZ1 Ref: 3.930 Measured: 3.935 Error Status: 0
FZ2 Ref: 3.932 Measured: 3.934 Error Status: 0

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.
