NTEP Certification and 'Legal for Trade' Compliance
Under federal and state weights and measures laws, any scale used to determine commercial pricing based on weight (e.g. buying gold, charging freight, selling bulk agricultural grains) must hold National Type Evaluation Program (NTEP) certification. Certified technicians perform annual calibration audits using NIST-traceable certified test weights to apply official state inspection security seals.
How to Calibrate an Industrial Digital Scale in 4 Steps
Standard calibration procedure using certified test masses.
Step 1: Level the Scale Using Adjustable Rubber Feet and Bubble Indicator
Ensure the center level bubble sits squarely inside the target ring.
Step 2: Enter Digital Calibration Parameter Mode (CAL)
Press and hold the Zero/Cal key combination to access internal span calibration.
Step 3: Capture Zero Point and Place NIST Certified Test Weights
Confirm zero reference point, then load calibrated test weights (e.g. 50 lbs).
Step 4: Save Span Calibration and Affix Tamper-Evident Security Seal
Lock the calibration switch and log the calibration record in company quality audit files.
Frequently Asked Questions (7 Questions Answered)
Q1: What does NTEP certified mean on a scale?
NTEP (National Type Evaluation Program) certification confirms that a scale meets strict accuracy and performance standards, making it legal for commercial buying and selling transactions.
Q2: How often do industrial scales need to be calibrated?
Commercial scales should be calibrated annually for standard legal-for-trade certification, and quarterly or monthly in high-volume manufacturing environments.
Q3: What is a load cell in an industrial scale?
A load cell is an electronic transducer that converts mechanical compressive force into a measurable electrical voltage signal proportional to the applied weight.
Q4: Can digital floor scales withstand forklifts driving over them?
Yes, diamond-plate steel floor scales feature heavy structural channel under-ribbing and rugged shear-beam load cells designed to withstand heavy forklift traffic.
Q5: What is a parts counting scale?
A counting scale calculates the average piece weight (APW) of a single small item (like a bolt or pill) and counts thousands of identical pieces simultaneously by total weight.
Q6: What causes an industrial scale to drift or lose accuracy?
Uneven floor leveling, extreme temperature shifts, damaged load cell cables, electronic moisture ingress, and physical overload shock cause accuracy drift.
Q7: What is the difference between calibration and verification?
Calibration adjusts the scale to ensure its readings match certified test weights, whereas verification simply checks whether the scale is currently within acceptable tolerance limits.
