The SMC PME-100 measures the voltage drop at the tested section while a known amount of DC current is injected. The resistance value is immediately calculated and shown by a 3 1/2 digit liquid crystal display directly in Ohms, milliOhms or microOhms, depending on the scale selected.
The measurement is carried out using the 4-wire method, also referred to as 'Kelvin Connection', to eliminate the influence of connections. The internal rechargeable battery supplies the necessary working power and up to 100A pure DC injection for extremely accurate measurements of resistance as small as 100 nanoOhms.
Easy to use, ideal for field, laboratory, and production line applications.
