Frequently Asked Questions
What is NTEP?
The National Type Evaluation Program (NTEP) is an evaluation program administered by the National Conference on Weights and Measures (NCWM).
Type evaluation is the process whereby weighing and measuring devices are extensively examined to determine if the performance, operating characteristics, features and options of a particular device complies with the applicable requirements of the National Institute of Standards and Technology (NIST) Handbook 44.
What does Legal For Trade mean?
Refers to the fact that a scale has passed NTEP evaluation and has received a Certificate of Conformance (COC). Often stated by the manufacturer as “NTEP Approved, Legal for Trade.”
What exactly does it mean when a scale’s capacity is stated as 5,000 lb x 1 lb?
This means that the total weighing capacity of the scale is 5,000 pounds, and 1 pound is the smallest increment of weight that the scale will display.
Do I need an NTEP scale?
If you will be using the scale in commerce, most states require an NTEP approved scale. The four states that do not require NTEP COC are North Dakota, Texas, Vermont, and Rhode Island.
What size weighing deck/platform do I need to for weighing pallets?
We recommend a 4 ft. x 4 ft. deck. Our economical PSC floor scale is ideal for pallet weighing and general industrial use.
What is NEMA 4X?
NEMA 4X refers to an electrical enclosure rating based on requirements stated by the National Electrical Manufacturers Association (NEMA).
A NEMA 4X enclosure is an enclosure constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against corrosion, falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external formation of ice on the enclosure.
What is calibration?
Calibration is the process of adjusting the components of a scale so that it will accurately indicate zero, and accurately indicate weight in accordance with its capacity.
Do I need to calibrate my scale or is it factory calibrated?
All scales are factory calibrated before shipment to ensure accurate weighing.
When does a scale need to be recalibrated?
Most companies have a calibration policy to comply with their ISO or Quality System Procedures. NIST (National Institute of Standards and Technology) recommends a yearly calibration to ensure accurate weighing.
Is recalibration covered under warranty?
No, recalibration is the user’s responsibility.
Do scales interface with a printer?
Yes, most of our scales can be interfaced to a compatible printer. For details, please contact us and we will be glad to assist you.
