SAFETY
Caution: Refer to accompanying notes Risk of electric shock.
Equipment complies with relevant EU Directive
SAFETY WARNINGS
Safety Warnings and Precautions must be read and understood before the instrument is used. They must be observed during use.
For safety, PAT4 must be properly earthed. Only use a supply socket that has a protective earth contact. If there is any doubt as to
the effectiveness of the supply socket earth, connect a known good earth to the earthing point on the PAT4 front panel.
Test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation. The flash test probe must
be held behind the handguard, and only be connected to the PAT4 for the duration of the test.
For safety, tests are performed in the correct order. If an asset (appliance) fails a test, PAT4 will fail the asset and exit the test sequence.
The fault causing the failure must be corrected before the appliance is re-tested.
During testing, ensure that no hazard will exist if the asset operates as a result of normal running, or of a fault condition.
Assets should not be routinely flash tested.
Where assets have to be flash tested, see ‘Flash Testing – Warnings’ on page 11.
When performing an Insulation test the asset must not be touched.
Only perform an Operation test after an Earth Bond Test (Class 1 only) and Insulation Test (Class 1 or Class 2) have been verified.
The instrument should not be used if any part of it is damaged.
Replacement fuses must be of the correct type and rating. See ‘Fuses’ section.
NOTE: THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSON

The PAT4 Portable Appliance Testers provide significant advances in the ease of use, with features designed to speed up the testing of electrical equipment. The instruments meet the testing requirements of the UK Electricity at Work Regulations and the IEE Code of Practice for In Service Inspection and Testing of Electrical Equipment. The instruments may be used stand alone, or for maximum advantage, with PC based software, such as
XPressTMsoftware for WindowsTM(See
Accessories). The integral real time clock ‘stamps’ an accurate time and date on every test. PAT4 utilises a unique concept known as Test Groups. This permits very rapid addition and testing of equipment with a minimum of data entry. Once set up, the use of Test Groups will save a great deal of time. Additionally, Test Groups ensure that only the correct tests can be applied to the equipment under test and eliminate the need for complex test codes.
PAT4 provides a professional system for the rapid testing of equipment while maintaining the essential traceability of asset test history. The on-board Asset (Appliance) database keeps a record of appliance details, re-test frequency, test and re-test dates, and allows the previous test results to be displayed at the time of test. As well as the easy to use QWERTY keyboard, each field is named, so there is less chance of entering the wrong information. Data entry via optional bar code scanners is also possible. The lithium backed ‘real time’ clock maintains the time and date accurately for over ten years and automatically date and time stamps every asset tested. Data is stored in battery backed, solid state memory that under normal circumstances will be protected for ten years. Such storage media is however susceptible to external influences such as transients and static discharge. These effects may cause data corruption or loss.
Megger Limited cannot accept responsibility for any such losses of data. When the
PAT4 is used with PC software such as
XPressTMsoftware, employing good working practices, such as
the regular downloading of data will substantially reduce the risk.
The following information can be stored and accessed directly on the
PAT4.

Results (sets of) 1000

The instruments can perform the following tests:
Visual Inspection list
Insulation test
Fuse Test
Operation test.
Circuit test (pre-test)
Earth leakage test.
Earth Bond test
Extension Lead test.
Earth Continuity test
Flash test (PAT4 DVF only).
Due to the often harsh electrical environments in which Portable Appliance Testers are used and the likelihood of testing faulty equipment all Megger Portable Appliance Testers are protected by appropriate internal fuses. This ensures that the instrument is protected from serious damage.

General Description
An unfortunate downside to using internal protection fuses is that the PAT4 can be rendered inoperative simply by the failure of such a fuse resulting in frustration and delay for the user. In order to ensure that the instrument can quickly be put back into service without downgrading its protection externally located fuses are now fitted to all new PAT4 models. These may be changed quickly and simply by the user in the event of a failure. For maximum convenience all fuses are of the same value.
Additionally the PAT4 display will now indicate which fuse has failed, unless of course it is main supply fuse in which case the screen will be blank.
Replacement of Fuses
Always disconnect the PAT4 from the main supply before checking fuses. Use correct replacement fuses as printed adjacent to the fuse
Megger Part No. for replacement fuses 25950-014
Using your PAT4
Connecting to the Power supply
Plug the
PAT4 into a standard 230 V supply for testing 230V appliances or into a 110V supply for testing 110V appliances. A 110V ‘site’ or ‘tool’ transformer may be used.
On connecting to the supply, the
PAT4 performs a rapid self-test and calibration sequence. If the screen is dim, refer to Contrast adjust.
* For 230 V 60Hz operation see note on Earth Leakage, page 45

Each test can be performed for a User definable time of between 5 and 60 seconds (5 and 20 seconds for Bond test). This enables specific tests to be set to appropriate lengths of time, perhaps to satisfy a particular standard. Once set, a test time will automatically be applied to all assets using such a test, regardless of the Group, Client or Location.

Barcode Scanner
The optional PAT4 barcode scanner (6231-623) can be used to speed up the collection of asset data.
On subsequent visits it can also allow rapid retrieval of stored asset details when used in conjunction with barcoded asset labels.
PowerSuite
T
M
can be used to produce custom barcode labels, or alternatively pre-printed barcode asset labels are available from
Megger Limited (see Optional Accessories) and other sources.
The scanner is pre-programmed at the factory to interface with the
PAT4, and it will read the following bar code formats: Standard
Code 39, Code 128, Codabar, UPC-A/E, EAN-13, EAN-8.
The
PAT4 needs no setting up to use the barcode scanner, simply plug it into the 9-way D-type connector on the front panel of the
PAT4. The scanner will bleep a few times when it powers up.
The
PAT4 is set up to read barcodes when testing, editing or adding assets for the following fields:
Asset ID, Serial number, Asset Description and Group ID. When a barcode is scanned in these fields, the existing data is overwritten by the data that has been scanned in, and the OK key is deemed to have been pressed.
To scan a bar code, hold the scanner so that the ‘mouth’ of the scanner is parallel with the barcode and close enough so that the light from the scanner is illuminating the barcode. The scanner should read the barcode automatically (the trigger button on the scanner is disabled). The scanner gives a short bleep when it reads a barcode.
If a barcode is scanned which is longer than the data field in the
PAT4, the data received will be truncated.
In order to be able to scan Asset Descriptions and Group ID’s, you will need to prepare a sheet containing the text barcodes you wish to enter.
PowerSuiteTMcan print these barcodes.

Clients and Locations
PAT4 maintains separate sets of assets (appliances) testing records by Client. Each Client may be allocated several Locations where different sets of assets may be found. Up to 10 Clients and a total of 20 locations may be stored at any time.
CLIENT
LOCATION 1 LOCATION 2 LOCATION 3
LOCATION 1 LOCATION 2 LOCATION 3
Asset Records Asset Records Asset Records
This structure enables
PAT4 to separate the testing for each location, but maintains the overall traceability to the correct Client. It also
permits the same numbering sequences or asset IDs to be used for different Clients.
Where there is only one location, at least the Location name must be given; other address details can be omitted. Adding, editing or deleting of Clients and Locations can be performed either directly after Login, or from the Main screen.
