A test instrument used for circuit prototyping and calibration that allows a user to dial in a specific resistance, capacitance, or inductance value. Inside the enclosure, networks of precision components are wired to rotary switches, with each dial representing a decade multiplier (ones, tens, hundreds, thousands). It lets technicians quickly substitute exact values into a live circuit without soldering multiple discrete parts.
Grab the resistance decade box so we can figure out exactly what value the thermistor needs for this voltage divider.
