TISHUNT - Transducer Interface Shunt
This program is a utility with various functions related to shunts. The SWIFT
system includes the ability to connect a shunt resistor across each of the resistive
bridges in the transducer. This shunt function can be used as a simple verification
that the SWIFT system is working normally. Shunt verification activates the
shunts and compares the results to those recorded during calibration. While this
does not guarantee the transducer is still in calibration, it provides some level of
confidence it is working normally. If the shunt results differ significantly from
those recorded during calibration the SWIFT system should be evaluated for
possible problems.
Syntax
The tishunt command requires one argument, as follows:
tishunt port box
port is the communications
1 = COM1:
2 = COM2:
box is the SWIFT-TI communications address
1 = lowest possible address
9 = highest possible address
Example
The Shunt Main Menu options are described in the following paragraphs.
Initializing box...SWIFT TI Shunt Main Menu
0...exit
1...Read current Shunt values
2...Set the TI shunt tolerance
3...Restore Shunt parameters from a file
4...Scan inputs & outputs with shunts
5...Command a shunt cal
6...Write last shunt measurements to a parameter file
