The Model 350/355 default parameter setup does not ensure compliance with legal-for-trade installations as mandated
by local weights and measures authorities. This chapter contains information on NTEP and OIML regulations, sealing
and audit trails, and other requirements.
Since legal-for-trade requirements may vary, you must ensure that the Model 350/355 installed in accordance with all
local regulations.
NTEP Requirements
The National Type Evaluation Program (NTEP) is a widely accepted weights and measures standard in the United
States, with most states abiding by some or all of the NTEP requirements. A complete list of these regulations is
available in the “Handbook 44” publication distributed by the National Institute of Standards and Technology (NIST).
For more information, call (301) 975-3058, or visit
http://www.nist.gov .
The Model 350/355 NTEP Certificate of Conformance (C.O.C.) is 98-092A2.
In order to configure the Model 350 to comply with NTEP requirements, parameter P440-rstrc (restrict) must be
enabled. This ensures the following:
• Serial data will not be received while in the Setup Mode.
• Received alpha characters will not be displayed.
• Numeric tare entries cannot be received through the serial port.
• Pressing
# with a gross weight of zero (0) will not automatically switch to the net mode.
• Negative tare values are not accepted.
• Tare rounding is enforced.
• When the tare value is zero, the net mode is not selectable.
Where applicable, enabling the restrict parameter will over-ride the current setting of other parameters.
NTEP Panel Mount Requirements
In addition to all other NTEP requirements, the serial number of a panel mounted unit must be visible from the outside
front of the controller. The serial number on the Model 350 rear label must be engraved in the space provided on the
panel mount tag (see Figure 36). These serial numbers MUST match. The tag is designed to be applied to the top right
edge of the enclosure or to the lower right of the front of the unit. Drill pins (GSE part number 38-04-2960) are
supplied with the panel mount kit to mount the tag. The drill pins require a 1/16” hole.
If the counting feature is enabled, NTEP requires a label on the front of the indicator stating “The counting
feature is not legal for trade”. See Other Requirements on page 102 for other application specific
considerations.
