6 Legal for TradeThe Model 350/355 I.S. default parameter setup does not ensure compliance withlegal-for-trade installations as mandated by local weights and measures authorities.This chapter contains information on NTEP and OIML regulations, sealing and audittrails, and other requirements.Since legal-for-trade requirements may vary, you must ensure that the Model 350/355I.S. is installed in accordance with all local regulations.6.1 NTEP RequirementsThe National Type Evaluation Program (NTEP) is a widely accepted weights andmeasures standard in the United States, with most states abiding by some or all of theNTEP requirements. A complete list of these regulations is available in the "Handbook44" publication distributed by the National Institute of Standards and Technology(NIST). For more information visit http://www.nist.gov.In order to configure the Model 350/355 I.S. to comply with NTEP requirements,parameter P440-rstrc (restrict) must be enabled. This ensures the following:llllllSerial 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 [TARE] with a gross weight of zero (0) will not automatically switchto the net mode.Negative tare values are not accepted.Tare rounding is enforced.l When the tare value is zero, the net mode is not selectable.Where applicable, enabling the restrict parameter will over-ride the current setting ofother parameters.If the counting feature is enabled, NTEP requires a label on the front of the indicatorstating "The counting feature is not legal for trade".Most NTEP requirements will also apply. See the Other Requirements section foradditional considerations.6.2 OMIL RequirementsThe International Organization of Legal Metrology is an inter-governmental body whichharmonizes the national metrology regulations of its world wide members. A list ofregulation publications may be obtained from the Bureau International de MétrologieLégale (BIML) in Paris, France.In order to configure the Model 350 I.S. to comply with OIML requirements, parameterP410-Euro must be enabled. Doing so will ensure the following:Model 350 I.S. and Model 355 I.S. Service Manual 127
