Acxico1Pcs 0-9999 Ohm Simple Resistance Box Precision Variable Resistor For Physical Electricity Experiment Teaching

Can't wait to be able to use this on sensors to provide what PCM is looking for . Love that it covers suck a wide range of ohms to test with..

Checked resistance with a multimeter. Readings are very close to knob settings.

Worked as it should. It gets 4 stars due to the +/- connections not being banana insert connections. I used bits of wire with eyelets and gator clips in order to use for diagnostic procedures which isn't the most ideal but the tool itself works fantastic and it's price point is great.

Amazing. Very accurate readings

Being a HAM Radio Operator, I needed a device that I could use for dialing in resistance loads for calibrating devices like antenna analyzers etc… Worked and performed great!!! If you buy one and it doesn’t then send it back, because you may have received a bad one. Mine works great!!!

4 Variable resistors. 1k to 10k resistor did not work at all. The product appeared to be used and had scratches and wear marks all over it. Now I have to drive 20 minutes to the closest drop point. That's BS. You should give me shipping label for USPS. Amazon is sucking more and more everyday.

How could something so simple get so screwed up ??? The picture shows what is to be taken as the ubiquitous banana plug interface to the box, but that is NOT what they use. There is a plastic screw top (that completely screws off), but with no typical hole thru the stud (normally it screws up to a stop, revealing this hole). Additionally, the stud barely has an indention, so no form of banana plug will go in and hold. Essentially the posts are nearly useless and misrepresented in the pictures, with no explanation of this.The box otherwise if fine, insertion loss pretty low, < 0.5 ohm, and steps seem to be 1% or so. iF they had used actual banana plugs this would be 5 Star and low cost... as it is, I almost rated it 1 star. Bad thing, apparently all these types of inexpensive boxes (at least from Amazon), seem to come out of the same factory near as I can tell... so I don't know if you'll do better other than spending considerably more. A shame that a $0.50 part is such a premium commodity.

If you have any guage that uses ohms this will test it. This jeep had sat for 15 years exposed to the elements 15 miles from the coast. This allowed me to test the guages first ,ruling out any unnecessary expense.Price was excellent
