功能描述

Measuring device can also be programmed to detect equipment and low voltage switchgear, low voltage power distribution equipment, wire stringing bridge etc.. Test device has a variety of testing procedures in the preparation of the national standard, after the input parameters, the device can achieve a key to achieve a key detection. The user according to the measuring device can also be programmed to detect equipment and low voltage switchgear, low voltage power distribution equipment, wire stringing bridge etc.. Test device has a variety of testing procedures in the preparation of the national standard, after the input parameters, the device can achieve a key to achieve a key detection. Users in accordance with the requirements of the connected test line, click the program control button, the device can be automatically added to the rated current and voltage followed in accordance with national standards completed on all the detection equipment, such as contact resistance insulation and withstand voltage, analog power supply under the condition of mechanical and electrical protection device, response time, timing, lack of phase voltage loss of pressure test, switch action time, transformer protection environment simulation, test results, and the detection results to be displayed, stored and printed.

儀器特點

Measurement accuracy of the electric energy meter: the device can detect the whole function of the electric energy meter according to the national standard.

2) voltage, current, active power, reactive power, frequency, power factor, harmonic content, and other electrical parameters of the detection.

3) remote control operation (from the time of the instructions issued to the relay closed).

(4) remote signal detection (whether change and change time time).

5) voltage and voltage loss protection test.

6) temperature detection, gas sensor detection.

7) over current protection and grounding current protection.

8) switch amountshift simulation test.

9) program control detection of all items.

3 display function, the device uses a 8 inch color LCD touch screen, graphical interface, easy to learn, and to provide menu style help files.

4 automatic data entry function, the device can automatically identify and have memory function, as long as the user input model, automatic input parameters. Relevant test data can be stored in accordance with the user's requirements for a long time.
