Ohmmeter and Bond Tester
See Ohmmeter and Bond Tester ProductsAn ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements. Megohmmeters (aka megaohmmeter or in the case of a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms (Ω).

The R1L-B series Ohmmeter/Bonding Tester is a digital microohmmeter designed to measure resistances from 10 µΩ to 20 Ω. It is used in applications such as metal bonding, switch, circuit breaker, circuit resistance and other contact and connection resistance tests as well as higher resistance measurements for circuit analysis and resistor testing up to 20 Ω. The instruments utilize the four-terminal, Kelvin technique to eliminate errors caused by the resistance of the leads. Resistance readings are viewed on a 3 1/2 digit display, reading from 1.999 to 199.9.
