A state certified Service Company is needed to properly install and calibrate the NTEP scale.

Weights & Measures requires a Placed-In-Service Form be completed.

Calibration should be done before an inspector from Weights & Measures comes to seal the scale.


It is recommended to have the scale recalibrated once a year to ensure accuracy

At random an officer from Weights & Measures will visit to inspect the scale

If the scale fails inspection the business is subject to fine.
