I used to like “hook-type” probe used in oscilloscope , as this type is very convenient in testing small parts. You just hook the test clip and see the result in the display. But why most multitester (Digital or Analog) uses standard probe? I don’t really got the idea.
So, let’s build by ourselves the oscilloscope-like probe for our multitester (you can call multimeter, DMM, or whatever).
You will need 3 major parts:
- The connector head (to plug into your multitester)
- Cables (AWG 18 or bigger, prefer insulated to cover at last 300V)
- The “hook-type” (you can also call it spring clip type) probe
The minor parts needed:
- Soldering iron and other soldering tools
- Hairdryer or matches
- Time (few hours)
- Motivation (yeah!)
Ok, first, put the cable on the connector head. Mine has screw to lock, but I put extra solder to make sure it will tight there forever and ever. See, they will be there, won’t release even you pull it hard.
