Even if mains power is removed e.g. when moving around a site, if you have not logged out, the PAT4 will automatically return to the Main screen. -
Page 30: Historical Data
Historical Data PAT4 incorporates a historic data facility that enables previous test results to be viewed at the time of testing. This powerful feature enables you to spot any dangerous degradation of the appliance since its last test. Whilst previous and current test results may each be considered acceptable in their own right against the pre-defined limits, there are instances where two very different readings will indicate significant degradation of appliance safety. -
Page 31: Quick-Check
Quick-Check It is often useful to perform a particular test on an asset in isolation. If for instance an asset had previously failed a particular test and had subsequently been repaired it may be useful to verify the repair before commencing with a full test sequence. Alternatively the test could be used during repair in order to highlight the area at fault. -

Page 38: Earth Bond Test
Description of Tests Earth Bond Test In order to adequately test the integrity of the appliance earth conductor, high current (10A or 25A a.c.) is passed between the Earth Bond terminal and the appliance test socket earth pin. The current may be set to 10A or 25A (calibrated at 0.1). The PAT4 can store upto three separate earth bond test results for each asset test. -
Page 39: Circuit Test (Pre-Test)
Description of Tests Circuit Test. (Pre-Test) Prior to performing any of the main tests an initial check is performed to indicate an approximate value of appliance loop impedance. Abnormal results from this test displays a message indicating the conditions that may affect the validity of the tests to be performed, or where possible damage to the PAT4 may result. -
Page 40: Earth Leakage (Touch Current) Test
Description of Tests Earth Leakage (Touch Current) Test Note: the Earth Leakage (Touch Current) test is carried out concurrently with the Operation test. The earth leakage test determines whether any current is flowing to earth. Normally appliances should have no or very little earth leakage current. The PAT4 can also detect earth leakage in Class 2 (Double insulated) assets. -
Page 41: Flash Test (Pat4 Dvf Only)
Description of Tests Flash Test (PAT4 DVF only) A flash test (dielectric strength test) is usually a manufacturers type test and should not normally be carried out as a routine test. The test stresses the asset insulation, and can in some cases actually cause damage. However it may be advisable to perform a flash test if the asset concerned has been completely overhauled. -
