OPERATING MANUAL PAT-800/805 version 1.09 5
1 Safety
PAT-800 and PAT-805 meters are designed for performing check tests on electrical equipment,
providing measurement results which determine the safety status of tested devices. Therefore, in
order to provide conditions for correct operation and the correctness of the obtained results, the
following recommendations must be observed:

Before you proceed to operate the meter, acquaint yourself thoroughly with the present manual
and observe the safety regulations and specifications determined by the producer.

Any application that differs from those specified in the present manual may result in a damage to
the device and constitute a source of danger for the user.

PAT-800 and PAT-805 meters must be operated only by appropriately qualified personnel with
relevant certificates authorising the personnel to perform works on electric systems. Operating
the meter by unauthorised personnel may result in damage to the device and constitute a source
of danger for the user.

The instrument must not be used with installations or equipment situated in dangerous
environments, e.g. where fire or explosion hazards exist.

It is unacceptable to operate the following:

A damaged meter which is completely or partially out of order,

A meter with damaged test leads insulation,

A meter stored for an excessive period of time in disadvantageous conditions (e.g. excessive
humidity). If the meter has been transferred from a cool to a warm environment with a high
level of relative humidity, do not start measurements until the meter is warmed up to the
ambient temperature (approximately 30 minutes).

The meter may be supplied only from grounded mains sockets.

Before measurements may commence, make sure the test leads are connected to the
appropriate measurement sockets.

Do not touch the tested device during measurements.

Banana test sockets and the socket for testing IEC cables are protected against improper
connection to the voltage up to 300V AC for 60 seconds.

Repairs may be carried out only by an authorised service point.
NOTE!
Only standard and additional accessories for a given device should be used, as listed
in the "Equipment" section. Use of different accessories can lead to errors in the test
connection and can introduce additional measurement uncertainties.
NOTE!
The plug on the housing near handle must be always tightened. It can be unscrewed
only when the device is transported by an aeroplane.
Note:
Due to continuous development of the meter’s software, the actual appearance of the
display, in case of some of the functions, may slightly differ from the display presented
in this operating manual.
