The claim of 1% tolerance on the resistors inside is generally not an exaggeration. The numbers you get on an ACCURATE multimeter will generally be within spec with a single caveat: with all switches set to off you will still get about a .15 to .25 ohm reading depending on the probes being used. Basically what this means is on the very low ohm settings you will get somewhere between .2 to .4 added to the reading - in the case of mine when I measure 1-100 ohms I usually get about .3 or .4 added if using probes and about a .15 - to .2 when connected with good banana plugs. Once you pass 400 ohms this largely disappears, but just be weary that you need to subtract roughly .25 ohms off the actual reading you are getting in the very low resistance range. Simple math boys and girls - it's not the end of the world. I look at it as a 29th switch to test a multimeter on a very very low ohm resistance.
The simple truth is all of decade boxes of this type do this - I have seen many variations of this design cost anywhere between 40 -110 dollars and all of them have the same general 0.25 ohms added without any switches engaged - this box is one of the cheapest and it's every bit as effective as other resistance boxes of this type that cost double or almost triple what this does.
Being one of the cheaper versions of this type - this box is not the most strongly constructed in the world but as long as you take care of it - it will work fine. I'm not particularly thrilled by the quality of the banana connectors - but these could easily be replaced with better connectors. They seem to work fine, although I don't know how long they will last before needing to be replaced and/or re-soldered. Time will answer. The switches seem to be of fair quality but it probably would NOT be a good idea to get too rough with them.
Overall this is a very useful tool for not a lot of money - I definitely would buy this unit again. I took off one star for the accuracy category because in all fairness the much more expensive (and much larger) decade boxes don't really have this problem. However it's not a deal breaker and certainly good enough for government work (and then some). Recommended.
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.
