Measuring Equipment Maintenance and Calibration

Policy: Local agencies are responsible for equipment maintenance and calibration and are required to maintain equipment maintenance and calibration logs in a central file.

Regulation: USDA Nutrition Services Standard 2A6

Procedure/Additional Guidance: Scales and Measuring Boards Perform daily maintenance of scales as follows: ● Place scales on a hard, non-carpet surface. If the area is carpeted, place the scale on a piece of plywood or a standing base. ● Before weighing every participant, check that the scale balance is at zero, by moving the ounce and pound weights to zero until the arm rests in the center. Check digital scales to ensure zero reading. If scales do not balance at zero, notify supervisor for scale to be serviced. ● Clean scales with disinfectant as needed. Check for wear and broken or faulty parts. Avoid using the scales until repairs have been completed. ● Clean scales with disinfectant as needed. Check for wear and broken or faulty parts. Avoid using the scales until repairs have been completed.

Perform yearly maintenance of scales as follows: ● Inspection: Scales must be inspected yearly. The scales may be inspected by properly trained staff who are following manufactures instructions, the scales may be inspected by the Colorado Department of Agriculture (CDA) or a private company. o CDA inspection fees are dependent on the type of scale tested and can be $35, $50, or $65 per scale. To locate an inspector in your area, contact the Measurement Standards Office 303-869-9101. ▪ If scales pass inspection by CDA, an approval sticker will be dated and placed directly on your scale. ▪ If scales do not pass inspection by CDA, a blue Work Order sticker will be placed on your scale. Avoid using the scales until repairs have been completed.

● Calibration: If based on the inspection, the scale needs calibration, local agencies may calibrate scales per manufacturer instructions. Staff doing calibration must be properly trained and follow the manufacturer’s instructions. If the CDA determines calibration is needed, a list of companies that can calibrate the scale will be given to the local agency. The CDA does not calibrate scales. ● Record repairs, replacements, and yearly inspections on the maintenance log for each scale.

Perform daily maintenance of measuring boards as follows: ● Clean measuring boards with disinfectant as needed. ● Check for wear and broken or faulty parts. Avoid using measuring board until repairs have been completed.

Perform yearly maintenance of measuring boards to check all boards for accuracy as follows: ● Use a metal measuring tape to check for slippage on wall mounted boards; and ● Check the right angle on head and foot boards. ● Record repairs, replacements, and yearly inspections on the maintenance log for each measuring board.
