General
The specifications for the 4100 Series of Ohmmeters are listed in the following paragraphs. In all
cases the specifications are valid for full Kelvin Four-Terminal measurements using connections
having less than 20 milliohms of lead resistance per wire.
Accuracy
The accuracy specifications listed below are valid following a 30 minute warm-up at an ambient
temperature between 15
°C and 35°C for a period of 1 year following calibration, and include the
effects of line voltage variations within the allowed range.
