The verification main items comprise: appearance inspection, basic error verification, verification of lifting variation and zero deviation.
At present, a power meter used does not have a detection interface, so that a detector can only stop and power off, detach the power meter and send the power meter to a metering technical mechanism, and the power meter is verified in a laboratory by a checker and then gets back to be installed after the power meter is qualified. In the process, the power is cut off when the power meter is stopped, the power meter is disassembled and assembled, and road transportation consumes a large amount of manpower, financial resources and time, and faults of equipment and the power meter can be caused by the disassembly and assembly. In addition, the failure probability of the power meter is increased due to jolts, vibration and the like during transportation, particularly during return. Even if the field environment conditions meet the requirements of the verification regulations, the user needs to stop the machine, cut off the power supply and disconnect the connecting line between the binding post of the power meter and the equipment for verification.
Meanwhile, when the display data of the power meter is suspected to be problematic in the two tracing periods, the power meter can only be shut down and power-off, and the connecting line between the binding post of the power meter and the equipment is disconnected for inspection, so that certain manpower, financial resources and time are consumed.
