2 General description and features of the instrument
PAT-806-IT digital meter is intended to measure the basic parameters of portable electrical de-
vices (power tools, household appliances, etc.) important for their safety: protective conductor re-
sistance, insulation resistance, continuity of connections, the leakage current.
The meter may be used to test the equipment, in accordance with the following standards:

