1051 Time Electronics Resistance Decade Box, Resistance Resolution 0.01Ω, Absolute Maximum. The Time Electronic resistance decade box with UKAS calibration has resistance measurement ranges between 0.01ohm and 1Mohm. It is housed in a robust metal case with a removable protective rubber cover. It is designed to meet the requirements of both, industry and education. Excellent accuracy (mid-scale 0.1%) is achieved by using high stability metal film resistors. The 8-digit thumbwheel switch enables simple and precise setting with a clear indication of the resistance value.
