A laboratory resistance box, also known as a resistance decade box or resistance substitution box, is a device used in electrical and electronic laboratories to provide a known and adjustable resistance value for testing and calibration purposes. It allows users to simulate specific resistance values without the need for physically changing resistors.
Here are the key features and components typically found in a laboratory resistance box:
Resistance Range: A resistance box typically offers a wide range of resistance values that can be selected and adjusted as needed. The resistance values may vary from a few ohms to several megaohms, depending on the specific model.
Adjustment Mechanism: Most resistance boxes have mechanical switches or rotary dials that allow users to select and adjust the desired resistance value. Each switch or dial represents a digit or a fraction of the resistance value.
Accuracy and Precision: Resistance boxes are designed to provide precise and accurate resistance values within a specified tolerance. The accuracy of a resistance box is usually expressed as a percentage of the selected resistance value.
Switching Matrix: Inside the resistance box, there is a switching matrix that connects a series of precision resistors based on the selected resistance value. The switches enable the user to connect or disconnect resistors to achieve the desired resistance.
