IMPORTANT

CALIBRATION CHECK: Only qualified service personnel should perform this

procedure. Load cells have no user serviceable components and should not be tampered

with for any reason. Re-calibration is generally not required, but should be verified

periodically to ensure accuracy. The recommendation for calibration check is at least

once every 12 months, or as individual maintenance policy requires.

CAUTION

The integrated circuits and semiconductors on
the printed circuit boards may be damaged by

electrostatic discharge (ESD). Be sure to use

proper handling precautions at all times.
