RSP High Resistance Decade Box – RSP803HRB
The RSP High Resistance Box is a laboratory-grade resistance standard designed for high-resistance measurement, instrument verification, calibration, testing, and electrical measurement applications. Manufactured by Rathod Services Pune (RSP), the unit provides a selection of clearly identified high-resistance values through individual electrical terminals.
With resistance values extending from 10 MΩ to 200 GΩ, the High Resistance Box is suitable for applications where conventional resistance decade boxes do not provide sufficiently high resistance values. Its straightforward terminal-based design allows the required resistance value to be selected and connected directly to the measurement circuit.
Key Features of RSP High Resistance Box
- Very High Resistance Range: Provides selectable resistance values from 10 MΩ to 200 GΩ.
- Multiple Resistance Values: Includes 10 MΩ, 100 MΩ, 1 GΩ, 10 GΩ, 100 GΩ, and 200 GΩ resistance points.
- Individual Terminals: Each resistance value is provided through dedicated terminals for convenient electrical connection.
- Clear Value Identification: Resistance values are prominently marked on the front panel for quick and easy selection.
- Laboratory Testing Application: Suitable for high-resistance measurement and verification in electrical and electronics laboratories.
- Instrument Verification: Can be used as a reference resistance source for checking suitable resistance-measuring instruments.
- Robust Enclosure: Designed in a compact enclosure for organized laboratory and testing use.
- Simple Operation: The direct terminal configuration makes the unit easy to understand and operate.
Resistance Values
The RSP High Resistance Box provides the following nominal resistance values:
| Resistance Value | Equivalent |
|---|---|
| 10 MΩ | 10,000,000 Ω |
| 100 MΩ | 100,000,000 Ω |
| 1 GΩ | 1,000,000,000 Ω |
| 10 GΩ | 10,000,000,000 Ω |
| 100 GΩ | 100,000,000,000 Ω |
| 200 GΩ | 200,000,000,000 Ω |
This range makes the instrument particularly useful for high-resistance and insulation-related measurement applications where resistance values in the megaohm and gigaohm range need to be evaluated.
How Does a High Resistance Box Work?
A high resistance box provides known resistance values that can be introduced into an electrical measurement circuit.
The basic operating method is:
- Identify the required nominal resistance value on the front panel.
- Connect the measurement instrument to the corresponding resistance terminals.
- Apply the appropriate test conditions specified for the measuring instrument and resistance standard.
- Measure the resistance using a suitable high-resistance measuring instrument.
- Compare the measured value with the nominal/reference resistance value.
This allows the user to perform resistance verification, instrument checking, and measurement-system evaluation.
Note: Actual measurement accuracy depends on the specified tolerance, test voltage, environmental conditions, connection arrangement, and characteristics of the measuring instrument. These specifications should be confirmed from the product’s technical datasheet before making accuracy or calibration claims.
Applications of High Resistance Box
The RSP High Resistance Box can be used in a variety of electrical measurement, calibration, testing, and research applications, including:
1. Resistance Measurement Verification
Used as a known resistance reference for checking suitable high-resistance measuring instruments.
2. Calibration & Instrument Testing
Useful for laboratories involved in the verification and calibration of resistance meters, insulation resistance measuring systems, electrometers, and other suitable instruments.
3. Electrical & Electronics Testing
Can be incorporated into test setups requiring high-value resistance for circuit evaluation and measurement.
4. Insulation Testing Applications
High resistance values in the MΩ and GΩ ranges are relevant to insulation and leakage-current measurement systems, subject to the specifications of the test equipment.
5. Laboratory & Research Work
Suitable for engineering laboratories, R&D facilities, educational institutions, and measurement laboratories requiring controlled high-resistance values.
Construction & Front Panel
The RSP High Resistance Box features a compact enclosed construction with a clearly organized front panel. The panel incorporates individual red and black terminals associated with each resistance value.
The resistance values are clearly printed next to their respective terminals, allowing the operator to quickly identify and connect the required resistance point.
The enclosure provides a practical format for bench-top laboratory and calibration environments, while the accessible terminal arrangement simplifies connection to external measurement equipment.
Why Use a High Resistance Box?
A high resistance box provides a convenient way to introduce known high-resistance values into a test circuit without having to assemble individual high-value resistors for every measurement.
It can help laboratories and engineers:
- Check the performance of suitable resistance-measuring instruments.
- Establish known resistance points during testing.
- Perform comparative resistance measurements.
- Evaluate high-resistance measurement systems.
- Simplify laboratory test configurations.
- Support calibration and verification procedures.
