2 General description and features of the instrument
PAT-800 and PAT-805 digital meters are intended to measure the basic parameters of portable
electrical devices (power tools, household appliances, etc.) important for their safety: protective
conductor resistance, insulation resistance, continuity of connections, the leakage current.
The meter may be used to test the equipment, in accordance with the following standards:

