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 two (2) known calibrated weights, traceable to
NIST.
NOTE:
The first weight should be at least 500 pounds (half of the
maximum scale capacity). The second weight should be less than
half of the first weight.
DO NOT USE
barbells or un-calibrated
weights.
STEP 2:
Zero the scale by pressing and holding
ZERO / WEIGH
button.
STEP 3:
Place the first calibrated weight on the scale. Wait for
scale to stabilize; note scale reading. Remove weight.
STEP 4:
Place second calibrated weight on scale. Wait for scale to
stabilize; note scale reading. Remove weight.
STEP 5:
The scale readings for both weights should be within the
Calibration Tolerance plus or minus one digit of displayed resolution
(Figure 7).

IMPORTANT
CALIBRATION Qualified service personnel only should perform this procedure. The
SR565i-H 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.
