Mini Appliance Checker
The Mini Appliance Checker 880 AT is a simplified version of an appliance tester which uses low voltage and low current to perform its checks. This is not intended to be used to perform certification testing. It has been designed to be low cost and simple to use, but still has all the necessary basic functions to check a normal appliance. It has been designed to be utilized by people who need to check the good status of insulation and plug wiring. For example, before delivery of an appliance to a customer. This Mini Appliance Checker also can be utilized to confirm the problematic status of an appliance which needs servicing. This checker verifies that the resistance between the Line and Earth conductor connected to the appliance is more than 1 ohm. If this is not the case, the L-E LED will light up, showing a likely insulation fault between L-E. This checker verifies that the resistance between the Earth Chassis of the appliance and the Earth conductor (at the plug) connected to the appliance is less than 10 ohms. If this is not the case, the EARTH BOND LED will light up, showing a likely continuity fault between the earth at the plug and the chassis of the appliance. When these three conditions are satisfied, the GREEN LIGHT LED will light up, showing that the appliance has checked SAFE according to the checker method of testing. Always use the appliance simulator before and after using the checker on a real appliance, to ensure proper working condition of the checker.

Please note that due to the fact that this checker uses less than 10V for its test, faulty voltage dependent devices could be undetected.
