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 : Calibrated weight should be equal to or greater than the
maximum animal weight, not to exceed the maximum capacity
of the scale
.
DO NOT USE barbells or uncalibrated weights.
STEP 2 : Zero the scale by pressing and holding the
ZERO/WEIGH button.
STEP 3 : Place calibrated weights on the scale. Wait for scale to
stabilize and note scale reading. Remove weights.
STEP 4 : The scale reading should be within the Calibration Tolerance Table (Figure 4)
SETTING CALIBRATION:
STEP 1: Select known calibrated weights, traceable
to NIST.
NOTE :
Calibrated weight should be equal to or
greater than the maximum animal weight, not to
exceed the maximum capacity of the scale
. DO NOT
USE barbells or uncalibrated weights.
STEP 2: Remove the top platform and then the two
(2) screws holding the display to the frame.
STEP 3: Pull the display out from under the
platform and remove the eight (8) screws from the
display cover (Figure 3). Place the top platform back
on frame.
STEP 4: Press the calibration button. The display
will read “
CAL
”.
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.
