LCR T4 Handheld case

thingiverse

I bought one of these LCR-T4 meters recently they are really handy, the only draw back it has is it is rigged for a 9v battery, which never last as long and never cost the same as cheap AA batteries and 2 none of the designs i seen had a good way to hold it whikle you test something , i am often in the feild as much as the shop and so every thing needs a handle. so in the effort of killing two birds with one stone i put a handle in it and loaded it up with AA batteries , this design is also equipped to use rechargable batteries, which now makes it super handy ... the holes in the battery lid are so i can run more alligator clip wires out of the battery pack which makes this a multiuse tool as it will be a 1.2V,2.4V,3.6V4.8V,6V,7.2V 8.4V, and 9.6V battery pack .. this is done by accessing the battery taps in the battery pack.. you can also configure it for negative voltages which are great for building Op-Amp Circuits. print and assemble see my other battery box designs for battery and spring details. i piced up some aligator clips from harbor freight and cut them in half and soldered the wires to the 1 2 3 smt pads on the lcr meter.
