Measurement Back Clip (wristwatch model)
Modularized design, so that it better meets the operational requirements in different environments and matches different operational modes. This program is based on the wearable watch design. At the same time, it can be added with different ways to make the product more flexible, such as back clip, cell phone protective cover tablet, wear hanging and so on.

Core Function
- In the cell phone + back clip working mode, we can directly connect the back clip via Bluetooth on site, scan the new/old meter code, and utilize the power infrared to realize one-click reading of the meter code, and complete the one-click meter change operation.
- Reducing process flow, realizing one-click meter/box replacement, compressing the 7 steps of the original ticket into 3 steps, and reducing the time for meter replacement from 2 hours to 30 minutes.
- The cell phone application obtains the authority to set the parameters of the power meter and the on site power-off/on task ticket, connect back clip via Bluetooth, using the back clip power infrared to send meter connect or disconnect command. Combined with the electronic sealing of metering devices, it provides technical means for on-site inspection of electricity theft behaviors such as private tampering and short connection.

Product Advantages
The cell phone back clip is adapted to the marketing field operation APP and SGCC app, and the cell phone is used as the APP carrier to manipulate the clip, which can carry out on-site operations such as supplementary meter reading, parameter setting, and adjusting the tariffs, outages and resumptions, and it can replace the hadheld device to cover all the business scenarios of field operation.
Application Scenario
In order to enhance the rate of staff mobile handheld facilities and equipment provision, maximize the satisfaction of business needs, and improve the efficiency of on-site operations, we upgraded the staff mobile work terminals and promoted the "cell phone + back clip" work mode. At the same time, in order to focus on resource sharing and reject blind configuration and idle waste, the company carries out the pilot project of "cell phone + back clip" working mode and promotes its application in accordance with the construction principle of "unified planning and step-by-step implementation".
