[. . . ] Note for PATGuard Plus Users Re-test periods are downloaded with test results and are compared with re-test periods of existing Assets on PATGuard Plus or used as the re-test period for new Assets. This is to ensure that re-test periods are `synchronized' across the PAT system. Asset Upload from PATGuard Plus will also include the re-test period 40 How to view Test Results Select Manual Test Use the appropriate number key from the table to select a specific test or use the cursor to highlight the desired option. Performing a Manual Test After selecting the appropriate test the tester displays a screen from which you can set test parameters. The user can change an individual setting when the parameter is shown in inverse video. Use the left and right cursor keys to highlight a field on the display. Then use the up & down cursor keys to change the variable in the selected field. In-Situ Earth Bond Test When selecting an Earth Bond Test and setting the Test Current parameter to 100mA, the test can be performed in one of two ways. A Fast key IN_SITU TEST (which becomes ISOLATED TEST to return to the previous test mode) enables the user to select an In-Situ test Isolated Test This is a normal Earth Bond Test where the EUT is plugged into the Tester power socket and the Earth Bond lead is connected to the EUT. This is the default test. In ­ Situ Test This is an Earth Bond Test where the EUT is not plugged into the Tester power socket but remains powered up from its normal power socket. For this test to be correctly carried out, the Supernova Plus is required to be powered from an adjacent socket to the EUT's power socket. 41 How to view Test Results There are two stages to this test: 1. This is carried out by connecting the Earth Bond lead to the socket screw (which should be earthed) or an adjacent building earth to the EUT. During this stage of the test, a large icon showing the Earth Bond Probe and a mains socket outlet will be displayed. This is carried out by connecting the Earth Bond lead to the EUT earthed cover. During this stage of the test, a large icon showing the Earth Bond Probe attached to a mains power appliance will be displayed. Earth Bond Limit Calculator Earth Bond tests have an additional Fast Key; LIMIT CALC. Selecting this enables the User to set an accurate Earth Bond Test limit by specifying the cable parameters. In ­ Situ Touch Leakage Test The Touch Leakage Test can be performed without powering down the EUT and plugging it into the tester power socket. The only connection the User is required to make is to connect the Earth Bond Test lead to the exposed metal work of the EUT and then perform the test. 42 How to view Test Results Note When the connection icon is flashing you cannot change any settings. The settings cannot be changed for a test if you have performed that test from within an appliance sequence. For example after selecting Create Appliance No you can only change the Earth Bond settings on the first Earth Bond test, all subsequent Earth Bond test will conform to the same settings. Note In manual mode you will not get Abort Options, the test will simply stop the test and revert to the Meter display. If an Appliance Number has been created, the test result will be stored under the entered Appliance number. To store tests to memory select COMMENTS / SAVE RESULTS from the MANUAL TEST SELECTION screen 43 How to view Test Results Enter Comments/Save Results When you have completed testing the EUT, you can enter comments. Other Fast keys are available for use before entering Comments and storing results. 44 How to view Test Results Review Results Display the results from the test in tabular form: - A fast key is available to VIEW COMMENTS. Use the Red button to return to the previous menu. Results Comparison Selecting this option will cause the tester to search memory for a previously stored test result for the same Appliance and Site. If there is one the display will show a comparison of the two test results. [. . . ] Please note that values for Substitute Leakage may differ substantially from that of conventional Earth Leakage tests because of the way that the test is performed (e. g. it will be affected by the presence of Neutral-to-Earth suppression capacitors). 88 Flash Test This test can prove useful in situations where neither conventional Insulation nor Flash tests are acceptable methods of testing the insulation of the appliance. Flash Test Warning 1500V/3000V a. c. test voltage This test is used to determine that the insulation is of sufficient strength to prevent breakdown, particularly where high transient voltages are likely. This test can be omitted when testing equipment with component whose voltage withstand rating is insufficient to accommodate the test without damage. [. . . ]
