PAT-820 digital meter is used to measure the parameters of electrical equipment (power tools, white goods, etc.) which determine their safety: resistance of protective conductors, insulation resistance, continuity of connections, leakage current, power, automatic measurement of all RCD parameters. Meter allows fash test/high voltage test.
PAT-820 can be used to test the equipment performed in accordance with standards:
