PAT-806 digital meters are used to measure the parameters of portable electrical equipment (power tools, white goods, etc.) which determine their safety: resistance of protective conductors, insulation resistance, continuity of connections, leakage current, power. Specifically the instrument is dedicated to measure the welding equipment.
PAT-806 can be used to test the equipment performed in accordance with standards:
