It is tested and proved that the detector can emit sound and light alarm signals if the SF6 gas concentration is beyond 1000ppm, and if not, it can display the concentration according to three formats of 400 ppm, 600 ppm, and 800 ppm.

• 经实际测试该报警器能在SF_6气体浓度超过1000ppm时发出声、光报警信号，在未达到1000ppm时能按400ppm、600ppm、800ppm给出SF_6气体浓度。
