Product Description
Resistance Box (Plug Type) is of a superior quality Heavy Brass Metal Blocks Size 7/16" are bound to Bakelite Plate by means of nuts and screws securing rigid fixation and eliminating any chance of contact error creping due to loosening of plugs and lugs which are cut to fine taper and are interchangeable. Plug heads are machine moulded, of heavy insulated Bakelite in beautiful shapes. The boxes are made of Teak-wood and nicely polished. We are renowned as one of the staggering High Power Resistance Box Suppliers in India.
Great care is taken in preparing the wire wound resistance. Selected double Covered Eureka Wire is wound in Bakelite spools. Sufficient ageing and Heat Treatment is processed through to avoid any moisture effects. Solder Joints are sealed after calibration. The Decade Resistance Box is calibrated on imported Testing Bridge Accuracy 0.1%.
Versatile Resistance Calibration ToolThis decade resistance box is tailored for a broad spectrum of use cases, from laboratory calibration to educational experiments and medical equipment testing. Its 6-decade rotary dial switches offer fine-tuned resistance selection, ensuring reliable performance for precision work. Gold-plated terminals and clear, easy-to-read markings enhance both accuracy and user experience.
Robust Construction for LongevityBuilt with a sturdy Bakelite or metal casing, the unit is engineered to withstand frequent handling and varied environmental conditions. Its bench-top design and manual rotary controls make it suitable for demanding test environments. With low contact resistance and high insulation resistance, it's both safe and dependable.
Simple Operation, No Power NeededFunctioning as a completely passive device, this resistance box needs no external power source, offering instant resistance changes without delay. It accommodates banana plug connections for universal compatibility, allowing for quick setup and repeated, reliable operation during calibration, measurement, and test procedures.
FAQ's of Decade Resistance Box:
Q: How do I select the desired resistance value on the decade resistance box?
A: To set a specific resistance, rotate each decade dial to the preferred value. The combination across all six switches determines the total resistance, with steps ranging from 1 to 100 k. The selected resistance is instantly applied to the output terminals.
Q: What types of connections are supported by this resistance box?
A: The box features 4 mm banana plug sockets, accepting standard banana plugs. Gold-plated brass terminals ensure low contact resistance and reliable electrical connections for a variety of testing instruments.
Q: When should I use this decade resistance box in my laboratory setup?
A: Use the decade resistance box whenever a precise, variable resistance is required-for example, during the calibration of measuring instruments, testing circuits, educational demonstrations, or simulating resistive loads in medical devices.
Q: Where can this decade resistance box be installed or placed during operation?
A: This equipment is designed for bench-top use in laboratories, educational settings, or calibration workstations. Its robust casing and moderate dimensions allow easy placement without special mounting requirements.
Q: What benefits does the Bakelite or metal case provide?
A: The Bakelite or metal enclosure ensures mechanical durability and offers protection against impacts, spills, and electromagnetic interference. It helps to maintain high insulation resistance for user safety and device longevity.
Q: How much current and voltage can this resistance box handle safely?
A: The device supports a maximum current of 100 mA (subject to the dial setting), up to a 1W continuous load, and maximum operating voltages of 250V DC/AC. Adhering to these limits ensures safe operation and accuracy.
Q: What environments is the resistance box designed for?
A: It is suitable for use in environments with humidity up to 80% (non-condensing) and temperatures up to 60C, making it ideal for most standard laboratory and educational settings.
