General Considerations
In every commercial transaction involving the weighing of a commodity over a scale, accurate weights and proper weighing practices protect both the buyer and seller Buyer and seller have a right to equity The seller has a right to fair value The buyer can compare values

Commercial or Non-Commercial
Determination of Weight For the purchase or sale, barter or trade of any commodity or thing Of any commodity or thing upon which determination of a charge for service is based Includes devices such as parcel scales, shipping scales, and scales used in the payment of agricultural workers Normally occurs in the presence of the customer If not, a weighmaster certificate is required

Commercial or Non-Commercial
Weighing performed within a business as part of the manufacturing process Pre-packaging scales used for filling packages to a pre-determined weight The determination of charges for the transmission of letters or parcels of less than 150 pounds, except when that determination is made in the presence of the customer charged for the service

Role of Weights and Measures
Responsibility of the Weights and Measures Official Inspect, test and seal commercial scales that are correct Ensure that weighing practices protect the interests of all parties Remove scales from commercial use that are found to be incorrect

Theory of Tolerances Errorless value or performance is unattainable
Tolerances are established to fix the range of inaccuracy acceptable for commercial use “Tolerance values are so fixed that the permissible errors are sufficiently small that there is no serious injury to either the buyer or the seller of commodities, yet not so small as to make manufacturing or maintenance costs of equipment disproportionately high.” In summary, upon completion of this first module you should have learned: Mouse click Why society needs weights and measures Mouse click The various systems of weights and measures that have existed over the years Mouse click The history of weights and measures Mouse click The current organization and function of weights and measures programs in the United States and California Mouse click The general legal principles applicable to weights and measures officials and their work Mouse click

Tolerances CCR - Scales
Sets the tolerance limit for inaccuracy allowed for a particular device Acceptance Tolerance is generally one-half of maintenance tolerance and is applied to scales that are new or undergoing type approval Maintenance Tolerance permits an additional amount of deterioration before the scale is placed ‘out of service’.

Sealing When a device is found to be ‘correct’, it must be sealed before commercial use In addition to the familiar approval seal, most devices have provisions for security sealing mechanisms used by service agents to make adjustments and calibrations There are primarily three ways to secure the calibration and parameter mechanisms Although none will prevent access, they provide evidence of tampering In summary, upon completion of this first module you should have learned: Mouse click Why society needs weights and measures Mouse click The various systems of weights and measures that have existed over the years Mouse click The history of weights and measures Mouse click The current organization and function of weights and measures programs in the United States and California Mouse click The general legal principles applicable to weights and measures officials and their work Mouse click

The traditional method using a lead and wire seal
Physical Sealing The traditional method using a lead and wire seal Another method is with tamper-resistant or pressure sensitive seals. These will tear or transfer markings if an attempt is made to remove the seal If either of these seals are not intact, the integrity of device is compromised It is illegal to use an unsealed device in commerce Security Sealing In summary, upon completion of this first module you should have learned: Mouse click Why society needs weights and measures Mouse click The various systems of weights and measures that have existed over the years Mouse click The history of weights and measures Mouse click The current organization and function of weights and measures programs in the United States and California Mouse click The general legal principles applicable to weights and measures officials and their work Mouse click

Electronic Sealing Many electronic indicators are capable of calibration and parameter changes through the keyboard These are sealed with either a physical seal to a calibration switch or with an electronic ‘audit trail’ that is password secured The ‘audit trail’ has two counters that monitor access to the configuration parameters and the calibration parameters These counters increment each time a parameter is accessed In summary, upon completion of this first module you should have learned: Mouse click Why society needs weights and measures Mouse click The various systems of weights and measures that have existed over the years Mouse click The history of weights and measures Mouse click The current organization and function of weights and measures programs in the United States and California Mouse click The general legal principles applicable to weights and measures officials and their work Mouse click

Audit Trail Access The device type approval or certificate of conformance will indicate how the device is to be sealed When a device is sealed with audit trails, those numbers must be recorded on the certificate of inspection. Recording those numbers is how you, as an inspector, seal that device The device type approval or certificate of conformance will indicate how to access the audit trail numbers In summary, upon completion of this first module you should have learned: Mouse click Why society needs weights and measures Mouse click The various systems of weights and measures that have existed over the years Mouse click The history of weights and measures Mouse click The current organization and function of weights and measures programs in the United States and California Mouse click The general legal principles applicable to weights and measures officials and their work Mouse click

Audit Trail Verification
During routine inspection or complaint investigations, the audit trail numbers are accessed and compared to numbers from the previous inspection or service agency ‘placed in service’ reports Unauthorized or unreported access should be researched and action taken as in cases where physical security seals are compromised For information on responsibilities of Service Agencies and Agents refer to Module 14 In summary, upon completion of this first module you should have learned: Mouse click Why society needs weights and measures Mouse click The various systems of weights and measures that have existed over the years Mouse click The history of weights and measures Mouse click The current organization and function of weights and measures programs in the United States and California Mouse click The general legal principles applicable to weights and measures officials and their work Mouse click

Enforcement Actions Devices that do not meet the tolerances and specifications are removed from service with an ‘Out of Order’ tag. Some counties allow continued use if the device is against the seller A sealer may permit the use of an unsealed device pending repairs if the device is in error only to the disadvantage of the user and the user is always the seller. Such an unsealed device shall be repaired within 30 days. Check with your supervisor so you may follow your county procedures.
