This guide provides essential details on measuring AC and DC voltage, resistance, and current using multimeters. It covers voltage ranges up to 1000 volts for AC and DC, as well as millivolt measurements up to 400 millivolts. Learn the correct procedures for Ohm's resistance testing and diode testing, including the importance of turning off power where needed. We also address common setup errors to ensure accurate measurements, including switching positions and lead placements. Master multimeter usage with practical tips and best practices.
