INSTALLATION NOTES
Install the PE-1 on a flat and rigid mounting surface.
Use correct M3 fixing screws for the load cell body.
Do not exceed the maximum permissible load.
Avoid shock loading, side loading and cable damage.
For platform weighing, keep the load centered on the platform.
For tension use, align the tension force with the load cell centerline.
Use an overload stop when required by the mechanical design.
Perform calibration after installation.
