An automotive relay tester is a dedicated device based on PC measuring technology. The tested relay is powered by a controlled 20V DC / 200mA power supply with defined ascending and descending jumps. The device evaluates the voltage and current of the relay switch on and off. The standard universal program EfLab from our company was supplied to control the whole test.
