Depending on individual state law, the calibration feature of the scale may be required to be sealed by an NIST/NTEP
official. To seal the calibration feature, follow the instructions below.
The scale can be sealed in two ways by using either a paper
seal or a wire seal.
Paper Seal:
1. To seal the scale using a paper seal or a sticker, use a
flathead screwdriver to gently remove the calibration
wire seal screw located in the rear of the scale.
2. Once the wire seal screw has been removed and the
calibration switch exposed, gently insert the flush
sealing screw provided with the scale in the place of
the wire seal screw.
Warning: Do not attempt to screw the flush sealing screw
all the way in. Stop when the screw is flush with the
casing of the scale.
3. Once the flush sealing screw is in place, apply the paper
seal over it, so that it completely covers the flush screw.
Wire Seal:
1. To seal the scale using a wire seal, insert the wire into
the opening of the calibration wire seal screw.
2. Insert one end of the wire through the opening in the fixed rear foot located underneath the scale.
3. Bring both ends of the wires together and close the wire loop with a seal. Do not attempt to remove the calibration
screw as it will rip the wire and break the seal.
