RD-300 Resistance Decade Box

The RD-300 Resistance Decade Box is a convenient tool aiding you both in design and testing as well as calibration of your test equipment. When needed to determine the correct resistance value, the RD-300 offers 7 decades of resistance ranges, from 1 to over 11MΩ (in 1Ω steps). Slide switches allow for easy addition and subtraction of resistance values. Switches that are in the ON position are clearly marked by a white dot below it to easily distinguish it from those that are OFF. A rubber boot allows the user to prop up the unit for ease of viewing and changing of values.
