Breadboard-friendly Multimeter




Using breadboards I soon faced the problem of the multimeter probes too thick to be plugged in the breadboard holes for a stable and handless contact.
I had the idea to modify my multimeter in order it to be much easier to connect to the breadboard

Step 1: What You Need

the material needed for this project is
A multimeter: In my case a DT830B
(I choose a cheap one because I preferred not to endanger of destruction an expensive device)

Female dupont connector Jumper wire for standard 0.1" breakaway headers.

Soldering wire

Maybe a little of hot glue

The Tools needed are a
soldering iron
screw driver
maybe a drill and hot-glue gun

Step 2: Open the Multimeter

Unscrew the screws and open the multimeter case.
 If you can't  see any screw they are probably in the battery housing.

Step 3: Place the Header Outside the Case

make a hole in the plastic case.
I used the hot tip of the soldering iron to make the hole(use an old tip or replace the tip with a steel nail for this job, don't ruin a good soldering tip for this), otherwise you can use a drill or a dremel.

The hole can accomodate the wire plastic female header or just the wires if you prefer to glue the header outside the case.

In  my case i decided to place the header in the hole and hold it in place with the melted plastic from the case.
If you prefer you can hot-glue the connector outside the case

Step 4: Solder the Wires

Cut the wires ad the desired length
Strip the wires and solder the wires at the contacts of the traditional probes.

being interesten mainly in voltage and  resistence measurement and in any case in small current measurements I soldered all the white wires to the (V - Ohm - mA) contact.

Step 5: Close the Case, You Have Finished

The conversion is finished and your multimeter is now breadboard friendly.

    Nice idea. Ive been facing the same problem and been thinking on an easy way to fix it... I shouldve looked here before wasting my braincells :p Time to dig out some suitable wires!

    Thnx for sharing. Not only is it useful for breadboard but also for checking resistors n caps directly as shown in the pic.
