Hotkey to delete the account. 4) Press the Delete 5) The Warning message will be displayed. Press OK to confirm or Esc to abort. Notes: Deleting an account whilst logged into the same account will log the operator out of the PAT tester. 11.
Pressing OK will remove all users from the PAT400 and create a single Supervisor account. If necessary, contact your supervisor before continuing, or press ESC to abort. 4) Press OK to continue. 5) The display will show a standard warning screen. 6) Press OK after reading and understanding the warnings given. The PAT400 is now logged into a standard Default user account as a “Supervisor”.
12. Reverse L-N Polarity (not available on all instruments) In countries where the power plug can be reversed in the socket (example: Schuko) the earth leakage tests can be configured to test in normal “forward” polarity or “normal and reversed” polarity. Checking the “Reverse L-N Polarity” box in the “Add User”, “Edit User” or “Expert Options” screen enables the forward and reverse earth leakage testing. Reversing the test is performed automatically and the worse of the two results are recorded.
5) Press the SAVE Hotkey to store the changes. Operators who have “Supervisor” status or “Expert” user status may also configure the Reverse L-N Polarity feature in the Expert Options screen. 1) Use the UP or DOWN arrow key to highlight the Reverse L-N Polarity check box. 2) Press the OK key to enable or disable the reverse L-N testing.
3) Press the SAVE Hotkey to store the changes.
13. Measure PE Option (not available on all instruments) Some PAT testing practices allows the Protective Earth bond testing to be skipped if it is deem impossible to access an exposed PE contact area. For PAT testers configured to allow for such situation there is a “Measure PE Option” checkbox made available in the Expert Options screen. Changing the existing state of the “Measure PE Option” checkbox will cause the Save appear. User must press the hotkey to save the new status of the checkbox.
14. PAT4 compatibility The PAT400’s have additional test capability that does not exist on previous PAT testers. To maintain compatibility when transferring data between the PAT 4 and the PAT400s, the following should be considered: Test options The PAT400s include additional tests not available on the PAT4.
To ensure hardware and software compatibility, refer to the Megger website for latest PowerSuite software and PAT400 firmware revisions. www.megger.
15. Care and maintenance The PAT400 should only be opened or repaired by an approved Megger service centre or by Megger Instruments Limited. To clean the instrument; disconnect the instrument from the power supply then use a clean cloth dampened with water or isopropyl alcohol. To clean the display window only use a lint free cloth. For warranty repairs see appendix E.
16. Carry case The carry case for the appliance tester has a lead storage pouch in the lid of the case when opened. This is designed for basic lead and document storage. Further items can be stored in the pouch. If it becomes difficult to close the case, the storage pouch can be removed from inside the case and attached to the front using the straps on the reverse of the pouch.
Appendix A – Test types explained Each test group is constructed from a series of individual tests. The tests are selected depending on the electrical construction of the asset under test. The operator must understand the type of electrical construction of the asset before a correct selection of tests can be made. The tests available on the PAT400’s are as follows: A.
also fail due to increased resistance induced by long cable lengths. When a bond test fails the PAT400 will display a lead compensation table, allowing the pass limit to be modified. See section 3.11 and Appendix A.6 for further details on lead compensation. A.2 Insulation testing This is used to confirm there is separation between the live conductors (live and neutral) and any accessible conductive parts.
Also called absence of potential Test voltage: 230 Vac 50 Hz 9.99 mA 110 Vac 50 Hz 9.99 mA During this test the appliance under test is powered from its normal mains supply and the test lead and probe is connected to the PAT terminal. This probe is applied to any conductive parts on the appliance under test. This probe performs a current measurement with respect to earth. This test can also be performed on three phase appliances powered from their own supply. Warning: A.
A.6 Power lead/extension lead testing Power cords and extension leads are tested in a similar way. The principle differences are the need to use an extension lead adaptor when testing extension leads, as the lead must be looped back to the PAT400 to allow bond and polarity testing. Extension leads or power leads with surge protection should be tested with an Insulation test voltage of 250 V. This prevents the surge protection from operating and artificially failing the lead.
the equipment touching other earthed equipment or from touching the ground. Parallel earth paths affect measurement accuracy and in worst case situations can lead to equipment being passed as safe when there is no proper earth connection through the electrical outlet. b. A hardware fault in the PAT400 c. A combination of the above. Any reports of parallel paths should be investigated. Check to ensure If the BOND (continuity) lead is not connected to the null post on the PAT400.
