Frequently asked questions
What range does the K5090 low resistance ohmmeter cover?
Five manual ranges: 200mΩ, 2000mΩ, 20Ω, 200Ω and 2000Ω, with resolution from 0.1mΩ to 1Ω. Accuracy is ±(0.75% rdg. + 4 dgt.) on 200mΩ and ±(0.75% rdg. + 2 dgt.) on the other ranges.
Why does it use a 4-terminal input?
REED specifies the 4-terminal input for high accuracy on low resistance. The meter ships with 4-wire leads with 2 kelvin clips, and has a zero adjustment dial.
How is it powered?
The K5090 runs on 110V (50/60Hz) mains power, with fuse and built-in overload protection.
What is included?
4-wire leads with 2 kelvin clips, protective case, power cord and shoulder strap.
