  • RESISTANCE || Standard four decade resistance box used to calculate resistance - Accommodates most student experiments
  • RANGE || Ranges from 0 - 11,110 Ohms in increments of 1 Ohm - ±1% tolerance - Maximum power output of 2W - Lowest Amperage: 20mA - Highest Amperage: 700mA
  • EASY TO USE || Resistances are easily selected by the turn of a dial
  • NOT INCLUDED || At least 2 banana plug cords, alligator clips, a power supply, and at least 1 multi-meter are required for use but are not included
  • SAFE HANDLING || It is important to set the resistance high enough in order to maintain a power output that is less than 2W - Too much current could start a fire or melt part of the box - No safety fuse


This decade resistance substitution box provides 4 decade ranges as given below and total value 0 to 11110 Ohms with a resolution of 1 Ohm. Each decade is selected using rotary switch. All resistance values are of ±1% tolerance and with 0.5 watt resistors, 0.5555 watts is the theoretical maximum. At least 2 banana plug cords, alligator clips, a power supply, and at least 1 multi-meter are required for use but are not included.
It is important to set the resistance high enough in order to maintain a power output that is less than 2W.
Too much current could start a fire or melt part of the box.
No safety fuse.
Suggested experiments include Ohm's Law: Finding the Relationship Between Current and Voltage (Constant Resistance), Ohm's Law: Finding the Relationship Between Current and Resistance (Constant Voltage) and The Wheatstone Bridge: Determining the Resistance of an Unknown Resistor.

I work in the automotive industry. I use this all the time to simulate fuel level sensors, intake air temp sensors things like that. Just start out with max resistance work your way down watch the data list or the gauge.Its easy to use and understand. Casing is firm dosent feel flimsy. It's priced aproprietly.

Great product and pretty accurate as well. Works really well for automotive diagnostic testing.

Inexpensive tool that provides expensive quality! Works perfect, simple and accurate.

Easy to use with a nice fit-and-finish, clearly labeled, and within the stated 1% tolerance.Taps are provided before/after each dial, so that you don't necessarily need to reset unused dials to zero.But what would have made it twice as valuable is to provide values above 10K (11K can be achieved with this unit by turning all dials to their maximum values). The 1-10 Ohm dial isn't useful to me, as these are only .5W - not power resistors.An additional dial on the left with standard values woiuld have been useful (but is not provided): 4.7K, 5.6K, 6.8K, 10K, 22K, 47K, 100K, 180K, 480K, 680K, 1MThe low-values should be 100W power resistors to make them more useful (Or at a *minimum*, 3W)The user interface of spinning a dial is far better than tinkering with up/down switches to set each decade and a little better than the individual switches on the Elenco RS-500. But that device can achieve a much wider range of values and is far less-expensive.This box is higher quality, looks better, and is quite a bit larger, but although the Elenco looks/feels cheaper, it covers the same range and far more (all the way to 10M), so is more useful at half the price.

I use a number of these are they are perfect for what they are. They provide a basic restive load in a variety of increments. For quick checks on benchtop or even desktop setups it is ideal.

The one I ordered was in a slightly different configuration, but a quality product none the less. Price is a little steep for what your getting, but on par with others in this category. Everything well within advertised specifications.
