Model RDB-10 is a handheld 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 Ω to over 11 MΩ in 1 Ω 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.

Use Model RDB-10 to:

• Select resistance in series or in parallel combinations
• Substitute resistance in servicing applications
• Vary resistance levels in circuitry design
• Determine impedance, reactance, and frequency characteristics
• Ideal for classroom education
• Demonstrate Ohm’s Law and other effects by varying resistance
