/diy/ - Do It Yourself

Do a continuity check between rod and bracelet (multimeter or whatever). Low resistance is not required because it's not about amps but merely about charge exchange. There may be a resistor in the connection by design. Direct (independent) grounding of otherwise floating equipment is common practice for charge-related measurements, see pic. Anything that has to do with the mains supply is a 'dirty' ground that cannot be used as a valid reference potential.

Many modern multimeters have an open input at the most sensitive DC voltage range. The only termination is the internal ESD protection circuit. Use range-hold to lock it. Pic shows your zero reference.
