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:

EN 60974-4: Arc welding equipment - Part 4: Periodic inspection and testing.
EN 60745-1: Hand-held motor-operated electric tools. Safety. General requirements.
EN 61029: Safety of transportable motor-operated electric tools. General requirements.
EN 60335-1: Household and similar electrical appliances -Safety -Part 1: General requirements.
EN 60950: Safety of information technology equipment (IT Equipment).
VDE 0404-1: Prüf- und Messeinrichtungen zum Prüfen der elektrischen Sicherheit von elektrischen Geräten. Teil 1: Allgemeine Anforderungen.
VDE 0404-2: Prüf- und Messeinrichtungen zum Prüfen der elektrischen Sicherheit von elektrischen Geräten. Teil 2: Prüfeinrichtungen für Prüfungen nach Instandsetzung, Änderung oder für Wiederholungsprüfungen.
VDE 0701-0702 Prüfung nach Instandsetzung, Änderung elektrischer Geräte. Wiederholungsprüfung elektrischer Geräte. Allgemeine Anforderungen für die elektrische Sicherhei.
