AutoSet User Manual 1137200
Calibration 3-17
In comparing tonnages, you must consider the number of load cells used during
calibration and the number of strain link channels on your AutoSet. Table 3-6 shows the
ratio of each Load reading on a calibrated AutoSet to each calibration unit display. Ratios
may be 1/1, 1/2, or 1/4.
4.
If the tonnages displayed on your AutoSet and on the calibration unit differ, turn the
adjustment screw on gain potentiometer R144 clockwise to increase the tonnage reading
for the Left or Left Rear strain link or counterclockwise to decrease the tonnage reading.
5.
Continue cycling the press and adjusting potentiometer R144 until the tonnage shown in
the “Left” (AutoSet 1500) or “Left (Rear)” (AutoSet 1504) Load LED display on your
AutoSet matches the tonnage shown on the calibration unit. Then go to step 8.
6.
If the Load LED display stops incrementing, indicating that you have reached the 12-turn
limit on the adjustment screw, and you have not been able to increase the tonnage on your
AutoSet so it matches the tonnage on your calibration unit, you must change jumper J115
to its “HI” setting. To do so:
•
Power down the AutoSet
•
Remove the jumper from the two lower pins and place it over the two upper pins (see
Figure 3-9)
•
Power up the AutoSet
•
Cycle the press to display a tonnage reading

PRESS MUST BE STROKED AFTER EACH POTENTIOMETER ADJUSTMENT
You must stroke the press after each adjustment of the potentiometer. Stroking the press
clears the previous tonnage reading and refreshes the Load display with a new value.
Do not be concerned if tonnage values do not display immediately on your AutoSet.
Tonnage readings will appear if you keep turning the adjustment screw and cycling the
press.
