1. ii 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 Continuity amp bond testing Continuity and bond testing are both used to confirm the existence of a safety earth return path of a Class asset However they differ in how they work and both have their benefits and drawbacks Continuity low current or Soft testing This test uses a 200 mA test current at 4 to 5 Vdc The test current is low so that there is no risk of damaging earth connections that may only exist for functional rather than safety reasons High current Bond testing not available on the PAT410 Uses a 10 A or a 25 A AC test current at 8 9 V This test is used where concerns that an earth may be maintained by a few strands of wire or where poor surface contact by the probes or clips could give a misleading reading This test is frequently the preferred test by many organisations 68 iii iv v vi In situ bond testing In situ bond testing is the ability to measure the earth integrity of a class asset that is hard wired to the electrical supply Normally there would be no convenient method to connect the asset to the PAT400 without disconnecting

However the same Asset ID cannot be used in different locations under one client 67 12 13 To transfer data from the PAT4 to the PAT400 the transfer must be made using Megger PowerSuite Professional To ensure hardware and software compatibility refer to the Megger website for latest PowerSuite software and PAT400 firmware revisions www megger com 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 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 These are passed through the D loops on the outside of the case and secured to the underside of the pouch using the Velcro fixings An additional storage pouch is available from Megger Limited for extended storage such that there is a pouch on both the inside and outside of the carry case Appendix A Test types explained A 1 i
