Model RDB-10 is a hand held Resistance decade box that creates a specific resistance value using a combination of switches. Designed with accuracy to meet the needs of industry and education alike. The RDB-10 is a compact, convenient tool for aiding in engineering design and testing as well as calibration of test equipment. It offers 7 decades of resistance ranges, from 1 ohm to over 11 megaohm in 1 ohm steps. Easy-to-use slide switches allow for straightforward addition and subtraction of resistance values. RDB-10 is a passive device that requires no power source. The unit is housed in a rugged handheld enclosure with an impact resistant rubber boot. Ideal for service, prototype and experimental and educational use. Input terminals accept standard banana plugs, bare wires, spade lugs or alligator clip. 1 ohm to 11,111,110 ohm in 1 ohm steps resistance. 0.3 ohm internal resistance. 1 watt resistors Power. 2 binding posts connection. 32 to 122 degree F operating conditions temperature. <80 percent RH humidity. Measures 6" length by 3-11/16" width by 1-57/64" height.
