Seaward PAT2000i - Manual (Page 15)

• Ensure that the earth clip of the bonded earth test cable is securely attached to the
appliance. A poor connection may introduce arcing of the contact.
• The appliance will be automatically energised during the load test. Care should be
taken that no ill effects can occur when the appliance commences operation.
• Certain appliances may contain interference suppressors which may be damaged by
the flash test if their components are not rated to withstand this type of test. Under
these conditions the flash test may be skipped.
• Where it is unclear which class of insulation applies to the appliance being tested it is
recommended that the manufacturers operating instructions be consulted.
• It is recommended that the PAT2000i is periodically checked by testing an appliance
of known electrical characteristics or by using an approved check box.
• Tests should not be carried out while a printer or computer is connected to the
instruments serial port.
• The instrument is designed to output a nominal 230V or 110V only from the
appropriate socket and various features are incorporated to ensure this. It is extremely
dangerous to connect a 110V appliance to 230V and this must NOT be done in any
circumstances.
• The side panels are fitted with quick release fasteners to allow access to test leads
etc. Do not attempt to release any fasteners within the side enclosures.
• Some l.T. Equipment may require a low current earth screen test only.
OPERATING PROCEDURES
GENERAL
The PAT2000i is microprocessor controlled and is designed to be extremely user
friendly by asking a series of questions which will guide the operator through the testing
sequence.
The instrument will make clear statements concerning the test or condition of the
equipment and ask the operator to confirm or deny the status, e.g. in the case of setting
the test mode the display prompts automatic test ?Y/N.
The operator can use either the YES and NO keys or the Y and N characters in answer
to the required questions.
If the operator wishes to use the automatic test sequence he presses the Y and the
instrument records the choice and proceeds to the next step.
If the operator wishes to use the manual test mode he presses N.
In this case the display will present the message manual test mode? Y/N. The operator
then will press the Y to confirm that he wishes to use the manual test sequence. Should
the operator wish to change his mind he should press N and go back to the beginning
of the sequence.
If the PAT2000i has been unused for several months it is recommended that it be
switched on for 16 hours before use to ensure the memory backup battery is in a
healthy state of charge. Check memory for corruption and if in doubt clear before use.
