IMPORTANT
CALIBRATION CHECK Qualified service personnel only 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.
