7. Find the potentiometer (R25) for the right strain link (below potentiometer R17).
Go to Step 3 and repeat the procedure through Step 6 for the right strain link.
Right strain link connector is TB7. The jumper J7 sets gain for the right strain
link.
8. You are done with the calibration procedure, but you must do one more thing.
Switch the toggle switch from "operate" to "calfactor." Now you will see numbers
(not tonnage) in the "left" and "right" setpoint displays between 40 and 960
(tonnage displays say "CAL"). These are calfactor numbers. Record them (make
sure you record them as left and right) and save them. Then if you ever have to
replace the control board, you can simply set the switch to calibrate and adjust
each potentiometer screw until the calfactor number you recorded is displayed.
You will not have to go through the whole calibration process.
Record the gain setting as well. (For example, low gain–jumper to left, hi gain–jumper
to right.) The gain has to be set properly in order to set the right calfactor number.
Write the calibration and gain information right on the "AutoSet operating instructions"
label (pictured below) which is affixed to your unit.
Write your Calfactors and Gain Settings in these spaces.
9. Set the toggle switch back to operate. Calibration is finished and AutoSet is now
ready for use.
