5. as some advantages over the 500V test 1 The appliance must be switched ON for this test to be carried out For appliances that need mains voltage like a PC to be properly ON this is a better test than the 500V insulation test 2 Any surge protection devices fitted to the appliances will not interfere with this test as it is in its normal operating state 3 On some older appliances the IET Code of Practice claims that there is a possibility of damage with the 500V test For this reason the Leakage Current test is referred to as a soft test as there is no risk of damage The Load Current test is useful as a higher than normal current draw can indicate a faulty appliance This is advisable specially after an appliance has been repaired Before any testing is carried out it is very important to inspect the appliance Many faults e g a wrong value fuse or a wrongly wired plug can only be found by careful inspection Earth Leakage and Load Current Tester Issue 1 1 FIRST STOP SAFETY 7 OPERATION This instrument is very easy to use Simply plug into 230V mains using the IEC power lead that is supplied Plug the appliance under test into the 13 Amp socket on the front panel Switch the appliance ON taking any necessary precautions For example if this is a kettle make sure that there is some water in it If a power tool then it will start to work The image above shows an electric fire plugged into the meter and switche
