[0020] Multiple function keys are equidistantly slidably connected to the lower front part of the body, and multiple indicator lights are equidistantly fixed to the right end of the middle front part of the body.

[0021] The above technical solution allows the power outage line parameter tester to quickly complete some functions via function keys, and the on / off status of the power outage line parameter tester can be observed via indicator lights.

[0022] As a further description of the above technical solution:

[0023] A carrying strap is fixedly connected to the right side of the machine body, and a protective sleeve is fixedly connected to the outside of the carrying strap.

[0024] The above technical solution allows for improved grip comfort by attaching a protective sleeve to the outside of the carrying strap.

[0025] As a further description of the above technical solution:

[0026] Two card slots are equidistantly located on the left side of the device, and a charging port is located at the lower left end of the device.

[0027] The above technical solution uses a card slot for installing memory cards and a charging port for connecting the power supply to the power outage line parameter tester.

[0028] This utility model has the following beneficial effects:
