TOLERANCE TABLE
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.
STEP 1
: (Figure 5) Simultaneously press and hold the hidden calibration buttons on the label
(“
+
” and “
-
”)
.
The display will read “
HOLD TO CAL
” as the right hand digit counts down from
9 to 0 to enter the CAL mode.
STEP 2
: When in the CAL mode, press the “
ZERO
” button to zero
the display.
STEP 3
: Place a known calibrated weight, traceable to NIST, onto the
weighing surface and compare it to the displayed reading.
Note
: DO
NOT USE barbell weights or calibrate to a mechanical scale
.
STEP 4
: Use the “
+
” and “
-
” buttons to make any necessary
adjustments to the displayed value. The displayed value should
be within 0.1% of the calibrated weight, plus or minus 1 digit of
reading.
STEP 5
: When adjustments are completed: Press the “
HOLD
”
button to SAVE the settings, or press the “
WEIGH
” button to
CANCEL. Both choices will EXIT the CAL mode.

CAUTION
ESD: 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.
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. Recommendation for calibration check is at least once
every 12 months, or as individual maintenance policy requires.
