More advanced techs know how to use the Lo-Z (low impedance) mode on their voltmeter if it has one to help eliminate this. […]

They destroy customer satisfaction and reduce technician morale by causing long hours, resulting in unprofitability for companies and less earning opportunity for everyone.
