The lightning stroke counter providing compared to prior art, the utility model, by setting ground connection in lightning stroke counter
Testing circuit, can detect whether lightning stroke counter is successfully grounded and sends corresponding signal, thus playing protection counting thunder
The effect of device.
Brief description
Fig. 1 is the structured flowchart of lightning stroke counter provided by the utility model.
Fig. 2 is the circuit theory diagrams of lightning stroke counter provided by the utility model.
Specific embodiment
The utility model provides a kind of lightning stroke counter, for making the purpose of this utility model, technical scheme and effect more
