Note:
An attempt to install drivers in 64-bit Windows 8 may result in displaying "Installation
failed" message.
Cause: Windows 8 by default blocks drivers without a digital signature.
Solution: Disable the driver signature enforcement in Windows.
2 General description and features of the instrument
PAT-810/815/820 digital testers are intended to measure the basic parameters of portable elec-
trical devices (power tools, household appliances, etc.) important for their safety: protective conductor
resistance, insulation resistance, continuity of connections, leakage current and RCDs.
The testers may be used to test equipment in accordance with the following standards:
EN 60745-1 Hand-held motor-operated electric tools. Safety. Part 1: 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 Information technology equipment
–
Safety- Part 1: General requirements.
EN 61557-6 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V
d.c. - Equipment for testing, measuring or monitoring of protective measures - Part 6: Effective-
ness of residual current devices (RCD) in TT, TN and IT systems.
