Appendix 2: brief method introduction

1. Connect the signal generator with bus bar
Red wire connect with “bus bar”

red clip

; Black wire connects with

“ground” (black clip);

2. Turn on the power switch of the signal generator.
3. Insert the plug of the caliper with the input jack of the signal receiver.
4. Turn on the power switch of the signal receiver.
5. Strangulate the measured circuit using caliper.
6. Begin to test.
7. The LCD display “number”, ground resistance display in number 01-19

(from low to high). “01” means the ground resistance is too small, “19” means
well grounded, detect the grounded conditions according detailed value.
