Earth / Ground Test (version 1)
Green,Yellow,and Red.The "Green" one we connected to the COPPER ROD while the red and yellow one,we struck them on ground.
1. Set Range x1Ohm.
2. Press Red Button "Press to Test".
3. If the needle goes to the end of the scale(green meter),mean,the copper rod should be buried deeper.
4. If the needle is below than 2Ohm,meaning,the grounding is just good enough.
1 Copper Rod is about 6 feet long.Normally,a suitable deep for grounding is about 18 feet.So,3 Copper Rod is just good enough for grounding.
Make sure supply from transformer should be OFF state.
