Pick precise resistance values for design work with a Extech 380400 Resistance Decade Box. Drop it into a circuit in place of a fixed resistor, and tune performance without swapping parts.
Applications
Read the selected value directly from the switches. The Extech 380400 Resistance Decade Box lets you try standard values in seconds, so you can find the best result fast.
Switch reading and selection
Move from prototype to proof with fewer steps. Use the wide range and 1 Ω resolution to make small changes and check results on the bench.
When you finish, note the value shown and fit a fixed resistor of the same size in your design. This workflow keeps tests clear and repeatable, and it saves time during calibration.
