The EICO 1171 Resistance Decade Box is a vintage, American-made piece of test equipment used to provide variable electrical resistance in circuits for testing, calibration, and engineering design.
Product Details
The EICO 1171 is a passive device (requires no power source) that uses a series of internal resistors and selector switches to simulate specific resistance values.
Function: Provides a variable, precise electrical resistance value in a circuit, acting as a substitute for a physical resistor.
Decades: The "decade" in its name refers to the controls which correspond to the digits in a decimal number (e.g., units, tens, hundreds, etc.).
Accuracy: It features a 0.5% accuracy and 1W power rating.
Applications: It is useful in lab, workshop, and production environments for troubleshooting, calibrating equipment (like multimeters), and varying resistance levels in circuit design.
Connectivity: It uses binding posts or terminals that accept various connectors like standard banana plugs, bare wires, or alligator
This is one component from a large estate purchase so has not had extensive assessment.
