Digital Microohmmeters
The SMC PME-10 is a low resistance ohmmeter that is used to measure accurately the contact resistances of switches, circuits breakers, motor and transformers windings and others. The measurement is performed through the current evaluation and the voltage drop on the unknown resistance, with 4 wires to prevent the influence of contact and cable resistances. The result is internally converted by a highly accurate and stable electronic circuit and is sent to the 3 1/2 digit liquid crystal display, allowing a direct reading in Ohms or milliOhms, according to the selected scale.
The instrument 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 10A pure DC injection for extremely accurate measurements of resistance as small as 2 milliOhms. For smaller resistance values, the PME-100 can inject up to 100A DC when powered from the AC mains. Easy to use, ideal for field, laboratory, and production line applications.
Applications
The PME-10 and PME-100 microohmmeters are used to accurately measure the contact resistances of switches, circuit breakers, motor and transformers windings and other applications which require measurement of low resistance values.
