    The Elenco RS-500 Resistor Substitution Box work as advertised. It is easy to set the resistor values for use in testing electronic circuits.In the box are two items: The resistor substitution box and an instruction manual.The resistor substitution box is actually smaller than the description indicates (7 x 5 x 3 inches). I measured its dimensions as 5.75 x 3.75” x 2 inches. The box is made of plastic and has four rubber feet on the bottom. The included instruction manual in English, which describes the device, its operation and components inside well.The resistors measured within 1% tolerance as described.The binding post connectors can accommodate spade lugs, bare wires and banana plugs. This latter feature makes it easy to use common “banana plug” cable for connections to test circuits. (See the photos which show me connecting my own banana plug cables to the box.)The resistors are set up with values in increasing value decades (1s, 10s, 100s, 1,000s 10,000s, 100,000s, and 1,000,000s) from left to right. The box may be set to any value from 0 Ohms to 11,111,110 Ohms. Resistor values are 1x, 2x, 3x, 4x which provide values from “0” to “10” of the decade by turning the slide switch(es) associated with the desired value(s) up to the “IN” position. (In any decade, “0” is all switches “OUT. To select any other value, turn switches to “IN” and add the values.)After a few minutes, I found it very easy to set any desired value for the substitution. In my testing, I was able to set resistor values for my testing and changed as needed for more testing quickly.Bottom Line: The Elena RS-500 resistor Substitution Box appears to be built well and it performs exactly as it is described.

    Reviewed in Germany on September 2, 2020
    Vorher eine 13€ Widerstandsbox gekauft und völlig daneben gegriffen.

    Diese Box hier hat 1W 1% Wiederstände und geht bis 10mOhm!
    Die Wiederstände sind alle innerhalb der Toleranz.
    Die Bananenbuchsen sind von guter Qualität und es lassen sich auch Kabel festschrauben.
    Die Box verrutscht nicht und wackelt auch nicht beim Bedienen. Die Schalter machen einen guten Eindruck.

    Würde diesen Artikel jeden Hobby Elektroniker empfehlen.
