Among the earliest commercially successful German multimeters, the Gossen MAVOMETER combined the functions of voltmeter, ammeter, and ohmmeter into a single portable instrument. Introduced during the rapid expansion of electrical engineering and radio technology, it enabled technicians, laboratories, and educators to measure otherwise invisible electrical forces with remarkable precision for its era. Its mirrored scale helped reduce parallax error, while interchangeable external shunts and resistors expanded its measuring range. Instruments like this helped define twentieth-century electrical science before the arrival of digital electronics.
