Packing Scale check whether the certificate

    First, examine the quantitative packing scale has a valid certificate , dividing the value and effectiveness of weighing whether to meet the requirements.

    Second, the technical status check is in the normal scale ; components should be complete , not damaged ; metering lever , bearing units can swing freely.

    Third, each weighing , known mass of the object chain conveyor shall not exceed the maximum capacity of the scale , but also can not weigh less than weighing objects.

    Fourth, weighing as much as possible so that objects placed on the loading platform in the middle drag chain conveyor position , when the vehicle enters the weighing platform , the speed shall

not exceed 5km / h, and the brakes gently .

    Fifth, the vehicle stop, the first prediction of its weight , the first move to open the main tour thallium revelation calibrator , and then move to adjust the balance Vice

swim thallium , and close readings showing calibrator record .

    Six continuous weighing, check weighing empty zero drift and calibration every 10 to 20 times.

    Seven in the weighing process , shall not affect the weighing accuracy of the moving parts, such as balance adjustment and thallium .
