Taboo 6: Replacement of substitute weights during load testing

Consequences: As the test load, the weight can be increased or decreased according to the required percentage load. It is not convenient to use cement or iron substitutes to correctly determine the load, so that the measured current or voltage value is not accurate, and the balance coefficient is determined. Unbalanced load also affects the debugging of the overload switch.

Measures: When commissioning the load, the construction unit should prepare the weighing weight calculated according to the load plus 50% weight. The weight should be convenient for manual handling and adjustment.
