Versatile Decade Resistance SelectionThe plug-type resistance box offers a wide range of selectable resistance values from 1 Ohm to 10,000 Ohms, allowing precise incremental adjustments in both 4 or 5-decade configurations. This flexibility is particularly useful in laboratory experiments, circuit calibration, and educational demonstrations, accommodating diverse testing needs with reliable accuracy.
Durable and Safe ConstructionEngineered for bench-top applications, the resistance box features a sturdy outer body made from Bakelite or teakwood, and robust iron components. Each brass, nickel-plated plug comes with an insulated cap for user safety. The design ensures low contact resistance and ultrahigh insulation resistance, maintaining measurement fidelity and user protection during operation.
Designed for Precise Laboratory ApplicationsThis resistance box is specifically built for laboratory environments, supporting up to 250V and operating reliably up to 50C. It is well suited for educational, scientific, and calibration purposes, serving physics and electronics experiments with manual, plug-operated control and clear silk-screened markings for accurate resistance selection.
FAQ's of Resistance Box, Plug Type:
Q: How do I select and change the resistance value using this plug-type resistance box?
A: To change the resistance value, insert or remove the nickel-plated brass plugs into the appropriate sockets, which are clearly marked in decade steps. The total resistance is the sum of the unplugged sockets, allowing manual, precise selection within the range of 1 Ohm to 10,000 Ohms.
Q: What are the main benefits of using this resistance box in a laboratory setting?
A: The resistance box offers highly accurate resistance selection (1% tolerance), easy manual operation, clear labeling, and durable construction. Its low contact and high insulation resistance ensure safe and reliable use, making it excellent for calibration, physics experiments, and practical training.
Q: When is this plug-type resistance box most appropriately used?
A: This device is most suitable for use during laboratory experiments, electronics troubleshooting, calibration routines, and physics practicals, particularly when variable and accurate resistance settings are essential.
Q: Where should the resistance box be installed or placed during experiments?
A: The resistance box is designed as a bench-top instrument. Place it on a stable laboratory table, away from moisture and excessive heat, to maintain optimal accuracy and safety during use.
Q: What is the process for maintaining and caring for the resistance box?
A: Periodically clean the box and plugs with a dry cloth to prevent dust buildup. Ensure the plugs are fully inserted during use and always handle them by the insulated caps. Store the equipment in a dry environment, and avoid exposure to chemical spills or extreme temperatures.
Q: What materials are used in the construction, and how do they benefit the user?
A: The box is made from Bakelite or teakwood for the body, iron for mounting, and brass with nickel plating for plugs. These materials ensure durability, minimized contact resistance, safe handling, and a long service life, making the device a reliable tool for repeated laboratory use.
