AZ Dept. of Weight and Measures has Increased the Frequency of Scale Inspections

As of July 1, 2016 the Arizona Department of Weights and Measures officially became a component of the Department of Agriculture. This is a very common structure that is used by many other states in our nation, including nearly all of our adjoining states.

At Southwestern Scale Company we have seen an increase in the rate of scale inspections and we wanted to share this information with you.

Resulting there has seemed to be an increase in “red tags” being issued. A red tag means that the scale system is out of compliance and the scale is placed “Out of Service” which means it cannot be used for commercial trade until all of the non-compliance issues are remedied and the scale is re-certified by a Registered Service Representative or RSR (state certified technician) from a Registered Service Agent or RSA (state certified company).

If your scale is being used for commercial trade, your scale is your cash register.

Here are things you can do to help mitigate getting a “red tag”:

  • Make sure you have a seal on your indicator and that it has not been tampered with.
  • Keep the area in and around your scale free of debris which can cause your scale to weigh inaccurately.
  • Assure that your business location has a current device license and current BMF# (Business Multi-Function number)
  • Have your scale regularly calibrated and certified by a licensed scale company using weights that are certified by the ADWM.
  • Make sure that the proper amount of weight is being used to test your scale per NIST Handbook 44.
