i made an earthing pad connected to a ground rod and i bought a mastercraft multimeter at canadian tire i just don't get any readings and am wondering about good or bad multimeters i can get voltage readings when plugged into wall socket at 120 or a little less with this canadian machine but i get no readings of volts in my body ?? there are more and different settings on this meter than the ones shown on earthing just wondering where to get help or understanding of whether i have the right multimeter for the job of earthing it looked simple when i first was told about earthing an mats and ground rods but this is now a real problem for me
