Before starting the PAT Test using the PB500, you must carry out a full visual inspection. This involves ensuring that the appliance is in good condition with no damage. You also need to check the plug and any leads. You can see how to carry out a full visual inspection here: How to do a full visual inspection in a Class II appliance
To identify a Class II appliance you can look at the manufacturers label for the Class II or double insulated symbol. If you don’t see this on the manufacturers label you will need to check inside the plug, you will do this as part of the visual inspection anyway.
After the appliance has passed its visual inspection, turn on the PB500.
Insert the plug of the appliance into the socket on the front. Make sure the appliance power switch is in the on position if it has one.
Press the Class II button and the PB500 will automatically perform the insulation (Riso) test, and the leakage (Ileak) test.
Lo Load appears if the plug of the appliance has not been inserted into the socket of the PB500. Or if the appliance power on/off switch is in the Off position. Or on an appliance that does not have an on/off switch.
Turn the switch to the On position and the test sequence will continue.Don’t worry if the appliance doesn’t have an on/off switch. Simply press the Class II button again to start the test sequence.
If the PB500 screen displays PASS so this appliance has passed the portable appliance test.
Place a “Pass” label on the appliance and complete the relevant Portable Appliance Test Report sheet noting the screen readings.
