The PAT tester is a multifunctional measuring device designed for testing electrical safety in accordance with the standards EN 61557 and DIN VDE 0100. It offers many functions specifically designed for the inspection and assessment of electrical installations. The PAT tester can perform precise measurements of insulation resistance between live parts and ground. With special functions for RCDs, both Type A and AC-controlled residual current circuit breakers can be efficiently tested, ensuring the proper functioning of these vital protective devices.

The PAT tester allows for the quick and accurate measurement of loop resistance to ensure that, in the event of a fault current, sufficient resistance is present to ensure a safe disconnection. Additionally, a measurement of the protective conductor resistance allows for checking the continuity of conductors and connections. A graphical representation of the wiring helps the operator perform measurements accurately. 

The brightness of the display can be adjusted in 4 levels. An adjustable alarm tone warns of errors or exceeding the limit. The adjustable auto-off time of the PAT tester prevents unintentional battery discharge. The device comes with test leads that meet the specific requirements of CAT III / 600 V and CAT IV / 300V.

The PAT tester offers a user-friendly interface, clear display elements, and a robust construction to meet the requirements in various environments. By complying with international standards, it ensures a safe and reliable assessment of electrical installations according to the highest industry standards.

With our optional EVSE test adapters, tests can also be conducted on wall boxes and charging stations for electric vehicles.
