Ok this is my first post so apologies if this is inappropriate but I need some solid opinions from guys who know about house earthing
So me and my dad just moved into an old house and I was walking around with my multimeter in NCV setting and it starts beeping when I hold the meter up in the air.
Now I'm not talking a stray beep every now and then like a false reading, this thing beeps continuously until I bring it back down close to my body and immediately beeps again when I raise it up, I'm familiar with inductance and body capacitance and all that but this is spooky
It beeps when I put it close to the kitchen bench (which has a metal strip along the perimeter), as soon as I touch the metal it stops beeping
It beeps near his ACOUSTIC guitar strings which is sitting on a stand and stops once I touch the strings
It beeps near any metal plate such as a small metal poster or piece of metal rod I have laying around and again, stops once I touch them
It beeps near some of the door hinges too
Is my house not grounded properly or something because both our phones act weird and slow in the kitchen and in some spots around the house
Now I'm an electrical engineer so please don't tell me I'm using my meter wrong or that it's broken because it beeps everywhere it's supposed to (near mains plugs, lights, appliances) but I've never seen the NCV go this crazy around random things and I'm worried the house may need some attention
Thank you to anyone who reads this and chips in, all advice is appreciated.
