1.3.2.d Calibration compliance
The AccuCount II is designed to comply with the most stringent requirements of
Weights and Measures. It is designed to be accessible for calibration, and it can be
officially sealed.
If your locality requires a NIST/NTEP official to calibrate your AccuCount II, point
out your new scale when the officer visits.
1.3.2.e Sealing the scale
The AccuCount II scale can be sealed with security seals for your locality, to conform
to National Institute of Standards and Technology (NIST) Handbook 44 requirements.
NOTE It will not be possible to perform external calibrations once the scale is sealed
(see “Calibration” on page 4-13 for information about the external calibration modes).
To seal the scale
1 Disconnect the power adapter from the outlet and from the rear of the scale.
2 Remove the weighing pan, weighing pan support, and draft shield (if installed) from the scale.
3 Turn the scale upside down and remove the screw that covers the service switch.
NOTE Retain the screw for later reassembly.
4 Turn the scale upright; and then install the draft shield (required), the weighing pan support,
and the weighing pan (see steps 4 through 6 in “Installing the scale” on page 1-3).
5 Connect the power adapter to the rear of the scale and to the outlet (see step 10 in “Installing
the scale”).
6 After the scale has powered on, slide the front edge of the scale off the surface just enough to
expose the service switch screw hole.
7 Use a paper clip to reach up into the screw hole and press the service switch.
