7、derstood before the instrument is used. They must be observed during use. For safety, PAT4E must be properly earthed. Only use a supply socket that has a protective earth contact. Test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation. For safety

8、, tests are performed in the correct order. If an asset (appliance) fails a test, PAT4E 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 resul

9、t of normal running, or of a fault condition. When performing an Insulation test the asset must not be touched. Only perform an Operation test after an RPE Test (Class 1 only) and Insulation RISO Test (Class 1 or Class 2) have been verified. The instrument should not be used if any part of it is dam

10、aged. Replacement fuses must be of the correct type and rating. See Specification section. NOTE: THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSON RadioFans.CN 收音机爱 好者资料库 General Description. 4 The PAT4E Portable Appliance Testers provide significant advances in the ease of u

11、se, with comprehensive features designed to speed up the testing of electrical equipment. The instruments meets the testing requirements of the UK Electricity at Work Regulations, IEE Code of Practice for In Service Inspection and Testing of Electrical Equipment, VDE 0701 and NEN 3140 specifications

12、. The instruments may be used stand alone, or for maximum advantage, with PC based software, such as Form Filler T M for Windows T M (See Accessories). The integral real time clock “stamps” an accurate time and date on every test. PAT4E utilise a unique concept known as Test Groups. This permits ver

13、y 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. PAT4E pro

14、vides 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 displa

15、yed 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 year

16、s 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 m

17、ay cause data corruption or loss. Megger Limited cannot accept responsibility for any such losses of data. When the PAT4E is used with PC software such as Form Filler T M, employing good working practices, such as the regular downloading of data will substantially reduce the risk. The following info

21、lti - function Soft keys Display FUSES - 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 p

22、rotected from serious damage. 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 with

23、out 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

24、, 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 FS2 FS1 Quick

25、Start Guide. 6 This Quick Start guide is intended to show you how to select Clients and Locations and test appliances in the minimum of time. Other features may then be understood and investigated when convenient. In using this guide you will make use of the demonstration data that was loaded onto y

26、our instrument at the time of manufacture. Connecting to the Power supply Plug the PAT4E into a standard 230 V supply for testing. On connecting to the supply, the PAT4E performs a rapid self-test and calibration sequence. If the screen is dim, refer to “Contrast adjust”. Multi Function keys. ESCape

36、 COMMS MENU Main screen To summarise you have now selected Client = A.N. Other Client Location = Dover Site Auto Restart to Main screen The Client and Location need be selected only once for any particular site. PAT4E will assume the same settings until you deliberately logout from the Client. Even

37、if mains power is removed e.g. when moving around a site, if you have not logged out, the PAT4E will automatically return to the Main screen. You are now ready to test appliances. Test appliances The use of test Groups, enables assets to be added to the PAT4E database, and select tests for the asset

38、s to be tested. PAT4E allows you to enter many details about the assets, or just an ID number and test Group. Once details are entered they remain with the appliance record, and never need to be re-entered, even when the appliance is re-tested at a later date. We recommend that full details of each

39、appliance are entered the first time it is tested since this enhances traceability and gives full advantage of the features in Form Filler T M 9. With the Main screen displayed, press the TESTS key. The Test screen is displayed. ADD Test SEARCH SELECT Test screen Since your asset will not already ex

Group Screen In order to test the asset (and other identical appliances) PAT4E needs to know what tests to apply and w

42、hat Pass / Fail limits are acceptable. This is achieved by allocating a test Group to the asset (50 different test Groups may be created on your PAT4E each of which can be applied to any number of appliances). Ten examples are included in the demonstration data (see Demonstration Data). One such gro

43、up created for typical Class 2 or double insulated equipment has been called TC2. 12. With the Group screen displayed, type TC2 and press the OK key . The message “Group TC2 Accepted” is briefly displayed, followed by the display of: Short cut to tests TEST CONTINUE You may press the CONTINUE key an

44、d enter full details for the asset. In this demonstration we will go straight to test the asset. 13. Press the TEST key. The Visual Inspection screen is shown Visual Inspection FAIL PASS Note: - Initially your PAT4E has been configured for Manual operation. This means that whilst the tests applied t

45、o the appliance are governed by the chosen Group, PAT4E allows the user to decide whether each test result is a Pass or a Fail. This allows greater control over the testing, and for you to proceed one step at a time. It also provides display of the historic data stored on the PAT4E. Once familiar wi

46、th the operation of the in PAT4E , you may choose to automate the test sequence to Pass or Fail each test according to the limits specified for the Group. This speeds up testing and is ideal where the operator may be unfamiliar with acceptable limits. 14. The first test specified for Group TC2 is th

47、e Visual inspection. Carry out a full visual inspection of the asset and if acceptable press the PASS key. The next specified test is displayed. If unacceptable, press the FAIL key and PAT4E will pose a number of questions enabling you to specify the nature of the fault as follows: Case OK? Plug OK?
