7.
Turn the potentiometer adjustment screw clockwise or counterclockwise, as shown in
Table 3-1, below, until the Load display for that channel reads b5 and -5. Try to
adjust the tonnage reading as close to zero as possible.
* The adjustment screw has a range of only twelve (12) turns in either direction. After this limit is reached, you can
continue to turn the screw, but the tonnage reading will not be affected.
† Strain links measure tension when mounted on straight-side presses or on the front of gap-frame (OBI or OBG)
presses (see Figure 2-9, page 2-11 and Figure 2-10, page 2-12)
‡ Strain links measure compression when mounted on the rear of gap-frame (OBI or OBG) presses (see Figure 2-9,
page 2-11)
8.
Remove each mounting screw from the strain link, apply removable-strength Loctite (i.e.,
No. 242 or equivalent) to the screw, and re-seat the screw in its tapped hole.
If the zero adjustment reading is greater than ±99, the message “HI” or “LO” will flash on
the Load LED display for that strain link until you have adjusted the reading to less than
±99 and reset the unit with the RESET button or DISPLAY switch, at which time the Load
LED display will show the offset to which you have adjusted the strain link. The Setpoints
LED display for the strain link will show the message “Err” until the zero adjustment
reading has been brought within the ±99 window and the unit has been reset, at which
time the Setpoints display will change to either “HI” or “LO.” The Setpoints display will
change to dashes (---) when the zero adjustment reading has been brought within ±50.

If you cannot use the LED displays on the AutoSet front panel to zero the strain links (i.e.,
displays are too far away or are obstructed), perform the
Using a Voltmeter to Zero Strain
Links procedure, page 3-4.
If you cannot get the Load display to read in the ±5 range, make sure strain link wiring
connections are tight and the connector is firmly seated. If loose connections are not the
problem, the strain link may not be working properly. Contact Wintriss Tech. Support for
assistance.
Make sure to use removable-strength Loctite (i.e., No. 242 or equivalent) on the mounting
screws. Do not use permanent-strength Loctite, which will prevent removal of the screws
if you need to remount the strain links.
