Resistance Standard

Resistance standards are devices used to accurately measure and calibrate electrical resistance. They are commonly used in electrical and electronic properties measuring and testing instruments. In the supply class Electrical And Electronic Properties Measuring And Testing Instruments, you can find various types of resistance standards, including:

1. Decade Resistance Boxes: These are portable devices that provide a range of precise resistance values in a compact form. They typically have multiple switches or dials that allow you to select the desired resistance value.

2. Precision Resistors: These are high-accuracy resistors that are specifically designed to have a very low tolerance and temperature coefficient. They are often used as reference resistors in calibration procedures.

3. Resistance Substitution Boxes: These devices allow you to substitute a known resistance value in place of an unknown resistance in a circuit. They are useful for troubleshooting and calibration purposes.

4. Resistance Decade Boxes: Similar to decade resistance boxes, these devices provide a range of resistance values, typically in decade increments. They are commonly used in laboratories and calibration facilities.

5. Resistance Standards: These are highly accurate and stable resistors that are used as reference standards for calibrating other resistance measuring instruments. They are typically traceable to national or international standards.

When selecting a resistance standard, it is important to consider factors such as accuracy, stability, temperature coefficient, and the required resistance range. Additionally, ensure that the resistance standard meets any specific standards or certifications required for your application.
