Extech380400 Resistance Decade Box

I checked all resistors on this decade box and all measurements fell into the stated accuracy range. Ready for testing.

Excelente

Solid resistor decade box, feels really nice on my hands, no a metal box but does not feel flimsy. Switches feel very solid, and all the switches external metal case are connected to ground. The yellow box looks nice on the bench. Does not take too much space.Some of these resistor decade boxes cost 100’s or 1000’s of Dollars, that’s crazy. Unless you are designing the next iPhone replacement, this is all you need. Resistor are 1%.The front panel cuts out are no precise. Look the 1MΩ switch, as a result the switch feels kind of rough when set to “IN” or “OUT.” This is the worse switch on the box I got. Some other switches are like that, but they don’t feel too bad.Overall, good box. I like it. I think 5 stars are well deserved. Price is good. Made in Taiwan. Where else, right?

A useful addition for anyone doing testing.

I received the XON 380400 Decade Box quite some time ago and have found it to be an excellent addition to my array of test equipment regarding the electronics work I do, (including designing circuits for a specific need and hobby related tinkering).I have been needing a resistance decade box for years but unfortunately no businesses around here sell this kind of device anymore.Some months ago I was browsing on Amazon and saw a number of listings for resistance decade boxes that personally looked well designed, at least from the outside.Anyway it soon became apparent that the price of these were a bit out of my budget however, I kept on searching and saw the XON 380400 decade box which certainly had the features I required.However as it was more affordable I decided to purchase the decade box and after a couple of weeks it arrived at my address.Later that week I carried out a number of tests on the box primarily to determine the resistance accuracy of all the internal resistors which were all said to be within 1% tolerance along with the (low) inherent resistance of the box itself.Well after testing with my good quality multimeter everything passed with flying colours. All resistance tolerances were well within spec.As well, the XON 380400 Decade Box is solidly built and the switches do appear to be of good quality also.Although somewhat pricey I would still certainly recommend it.
