APPENDIX C 9700W AUTO CALIBRATION
Tools required are a tape measure, masking tape, and marker pen. This allows for physical
measurement and references of the amount or length of wire feed.
You need to run the calibration at a speed near the upper limit and a speed near the lower limit.
Running two tests, one high and one low, allows the setting of the two extremes. This is important for the
proper operation and display values on the 9700W.
1) Backup the existing calibration numbers just in case of a mistake or you want to return to them. Do
this by going into the Calibration menu and making the Backup line item highlighted and then
pressing the right arrow key. This will copy the Calibration numbers from the main memory on the
9700-10 board to the backup location found on the Rabbit microcontroller board. (Note: If an error
is made and you want to restore the values before you started go to the Calibration menu and make
the Restore line item highlighted and then press the right arrow key).
2) Go into the Auto Calibration sub menu.
3) Choose a speed and time that you want to run the test for. Make sure that you have enough room
to feed wire for a reasonable length to measure. It is best if the final amount that should be feed is
a whole number just so you know how close the calibration is (i.e. 150 ipm of wire speed for 20
seconds should be 50 inches). Enter in the time and value for the wire feed speed to run.
4) Pressing the Start button causes the wire to feed. On the screen you will see the amount of time
left in the run and what speed the 9700W thinks that it is running. During the calibration run you
can stop the system by pressing either the left arrow key, the stop button or the estop button. You
will need a complete run to be able to recalculate the calibration numbers.
5) After the allotted time the screen will allow you to enter how much wire has been feed by entering
the data into the Actual line. (Note: Please make sure that you enter how much wire has feed and
NOT convert these numbers to inches per minute. The 9700W knows how long the calibration was
on for and will take care of that for you.)
6) Change the menu until the Set is highlighted. At this point press the right arrow and the 9700W will
do the calculations to change the input and output numbers. You can check by running again at the
same time and speed in item 3 or you can change to the other end of the calibration.
