• 1) What sectors are subjected to Mandatory Re- Examinations?

    Measuring devices in the below sectors are required to be inspected at set intervals. The sectors affected by these mandatory inspection frequencies are:

    Grain and Field Crops (inspection frequency every 1-2 years)

  • 2) Do I need to have my scale’s calibration checked?

    Yes. Depending on how the scale is being used, the frequency of the calibration checks can vary. If the scale is undergoing heavy use every day, then perhaps a calibration check and scale service should be done as often as once per month. Usually our customers have a calibration check/service done an average of 3 times per year. A Quality Program (ISO 9001, Grain Commission, etc…) can be another factor in determining the frequency of calibration. The frequency may be required as part of the quality program or governing standard you must meet.

    Finally, there is the consideration of possible non-accurate weighments and how this affects your company’s revenue. Typically your scale or scales can be considered a cash register for your company.

    If there is a problem with a scale it is usually that it is weighing light. This means you are losing $$$.


    Your scale is tested and found only 2kgs light on 1000kgs. (This may seem insignificant, until you do the math below).
    Your scale has a capacity of 10,000kgs and the product you are weighing is valued at $2.00/kg

    2kgs x 10 = 20kgs error on every 10,000kgs (20kgs x $2.00/kg = $ 40.00 lost revenue)

    You sell 100,000kgs/day = $400.00/day If you do this volume for 30 days your lost revenue is 30 days x $400.00 = $12,000.00

    Normally, if there is a problem with a scale (i.e.: scale binding), the heavier the load on the scale the worse the scale’s performance will be. The error could be 2kgs @ 1000kgs but at 10,000kgs the error could be 100kgs (100kgs x $2.00/kg = $200.00; 100,000kgs /day divided by 10,000kg loads = 10 loads x $ 200.00 = $2,000.00 lost revenue per day x 30 days = $ 60,000.00

    The importance of having your scale (cash register) weighing accurately is critical to the Profit of your business and the confidence your customers have in you.

    Preventive Maintenance will save you money in the long term and Increase Your Return on Investment.

  • 3) Do I need to have my scale examined?

    In Canada, if the scale is used in a “Legal for Trade” application, (i.e. money changes hands based on the scale’s weight reading) then the scale “MUST” be examined before it’s first use in trade. The examination must be performed by one of Measurement Canada’s Authorized Service Providers. Industrial Scale is an Authorized Service Provider and is accredited to perform scale examinations on behalf of Measurement Canada. For more information please call us @ 1-800-661-1588 or visit Measurement Canada’s website at the link below:


  • 4) Do I need to have my scale re-examined?

    First of all, we need to talk terminologies so that we are as clear as can be when we talk about examinations.

    Many people confuse the terms calibration and examination. Calibration is verifying that a scale weighs correctly; that is a 20kg weight weighs 20kg on the scale.

    At Industrial Scale we perform calibrations using certified test weights, all adjustments meet Measurement Canada allowable tolerances and we provide a scale test report with “As Found” and “ As Left” results on it. This report will meet all requirements for any Quality Program.

    An examination means the measuring device is verified using certified test weights and procedures. When verified the device has a Measurement Canada sticker and certificate and the results are sent to Measurement Canada.

    Industrial Scale Ltd. as a Measurement Canada Authorized Service Provider can provide all examination services to you as required below.

    Measurement Canada defines the first examination of a brand new scale as an “Initial Examination”.

    If that scale has another examination performed on it, then Measurement Canada defines the examination as a “Subsequent Examination”.

    If the scale is rejected by Measurement Canada, or fails an examination performed by an Authorized Service Provider and is repaired, the resulting examination is defined as a “Re- examination”.
