The Extech 380400 Resistance Decade Box is used for product design testing and calibration which can be substituted into a circuit and function in the place of any component with a standard value. Alternatively, it can be used to identify the best value for circuit operation then read that value from the switches. A resistor of the size indicated by the decade box switches can then be put into the circuit.
- Durable construction
- Case may be grounded separately
- 3 binding posts permit isolated substitutions
- 1% Resistance substitution from 1 to 11,111,110Ω
- Seven decade ranges of resistance
- Values can be set in 1Ω increments
