Calibration 3-1
Chapter 3. Calibration
This chapter shows you how to calibrate an AutoSet load analyzer so that it displays an
accurate reading of the tonnage applied by the press. You learn how to do the following:
1.
Adjust each strain link until it provides a “zero” signal with no load on the press,
following the instructions in
Zeroing Strain Links , below.
2.
Using a separate tonnage monitor and one or two load cells, apply a load to the press and
measure it, following the instructions in
Recording Tonnage on an AutoSet Calibration
Kit , page 3-5. You can use your own calibration gear, or rent an AutoSet 1500 calibration
kit from Wintriss.
3.
Determine the tonnage capacity of your press, and set the full-scale tonnage of your
AutoSet to that value, following the instructions in
Setting Full-scale Tonnage on Your
AutoSet , page 3-12.
4.
Adjust your AutoSet until its Load displays agree with the tonnage recorded on your
calibration unit, following the instructions in
Adjusting AutoSet to Read the Correct
Tonnage , page 3-15.
AutoSet should be calibrated after installation and whenever
•
Strain links are moved to a different location on the press
•
Tie rods are restressed
•
Major repair work is performed on the press frame
Before starting calibration, make sure the press is adjusted for optimal operation. Check to
make sure that the ram is parallel to the bed and that the gib/ways adjustment and tie rod
tension are correct.
Zeroing Strain Links
Before starting this procedure, make sure that the strain links have been mounted loosely on
the press and strain link cables have been wired to the appropriate connectors on the AutoSet
processor board as described in
Installing Strain Links , page 2-10. Then, to set the strain links
to read zero (0) at no load, do the following:
1.
Move the press ram to top dead center.
2.
Apply power to the AutoSet.
3.
Move the switch labelled S102 on the AutoSet processor board to the “ZERO SET”
position if S102 is not already at this setting (see Figure 2-4, or Figure 2-5 for location).
Check the Load and Setpoints LED displays on the AutoSet front panel.
Switch S102 should already have been set to “ZERO SET” during the power-up check.

Powering Up AutoSet , page 2-28.
