What if the meter in the home fails? Of course, it is to find the power company staff to carry out maintenance. However, when the power supply company staff shipped the meter back to the company for testing, the fault disappeared due to environmental changes. Therefore, it is very important to perform on-site verification of the meter. This also puts forward higher requirements for on-site calibration instruments.

In the past, the on-site calibration instrument can only check the accuracy of the energy meter. For other failures of the meter, such as skipping words and card characters, it cannot be detected on the spot. Recently, Baishan Power Supply Company developed a new single-phase energy meter on-site calibrator, named "LCF-CX106 single-phase energy meter on-site calibrator."

The advent of this instrument not only solves many problems in the on-site calibration, but also fills the blank of our country's electrical measuring instruments in this field. At present, the instrument is applying for a patent, and it is expected to be mass-produced in the future and put into more applications.

It is reported that the instrument is only the size of a small suitcase, but it can conduct on-site verification of the failure of the meter. As the current generator and power meter carrier communication detector are added to the design, the instrument can not only perform power meter accuracy verification but also perform on-site fault detection. This can not only prevent residents from paying more electricity due to meter jumping, but also prevent residents from losing power and causing losses to the company.
