When using scales to sell goods, you must ensure it is:
- An approved type of scale, suitable for its purpose
- Verified BEFORE use by a licenced technician or inspector
- The scale is level and is indicating zero before use
- Positioned so that the customer can easily see the measurement process (unless you provide a written statement of the measurement)
- Re-Verified after each adjustment or repair of the scale
How often am I required to Calibrate and Verify my Scale?
There is no law to define the time limit to verify or calibrate although the scales usage, the environment it is used in and the accuracy are all major factors when considering calibration. Calibrating scales often will ensure accuracy. We recommend calibrating your scales every 12 months to ensure accuracy. Scales can be calibrated yearly or monthly while others have daily spot checks.
What are the benefits of calibrating my scale?
- To ensure you are generating a profit from sales, rather than a loss
- To ensure accuracy for Trade Measurement Verified Scales
- To enable customers and businesses to have confidence in the results that they monitor record and subsequently control
Are my Scales Trade Approved?
Approved scales are marked with a National Standards Commission (NSC) or National Measurement Institute (NMI) approval number on the plate of the scale. Eg. NSC No. 6/4D/235 , NMI 6/4C/252. The Inspector who has verified your scale will place a sticker with the details of verification next to the plate.
