CALIBRATION
NOTE:
Ensure that nothing is in contact with the scale system during this procedure. Remove
hands from the system when noting the displayed calibration results.
CHECKING CALIBRATION
STEP 1:
Select known calibrated weights, traceable to NIST.
NOTE: DO NOT USE
barbells or un-calibrated weights.
STEP 2:
Zero the scale by pressing and holding the
ZERO/WEIGH
button.
STEP 3:
Place the calibrated weight on the scale. Wait for scale to
stabilize; note scale reading.
STEP 4:
Scale readings should be within Calibration Tolerance

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.
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.
