====== DIY adapter for using SMD test lead tweezer as capacimeter on a economic multimeter ====== ===== Adapter ===== {{:en:tinkering:labtools:p1140008.jpg?300|}} In economic multimeters the connectors for measuring capacitors they are not bushes but rather simple metal sheets. With few components I've built an adapter to be able to use a test lead tweezer on a multimeter. I am started from a faulty multimeter, from which I have unsoldered the bushings for test leads. Highlighted in yellow connectors in which to insert the capacitors to be measured, marked with red positions from which they were stolen bushings {{:en:tinkering:labtools:img_3794.jpg?300|}} Desoldered bushings {{:en:tinkering:labtools:img_3795.jpg?300|}} Cutted two small pieces of a copper clad for PCB, 20mm x 5mm x 1mm thickness {{:en:tinkering:labtools:img_3796.jpg?300|}} Temporarily fastened the bushing on the piece of copper clad using a copper wire {{:en:tinkering:labtools:img_3799.jpg?300|}} The two bushings soldered on the copper clad {{:en:tinkering:labtools:img_3804.jpg?300|}} With the adapter you can now measure the SMD capacitors {{:en:tinkering:labtools:p1140014.jpg?300|}} {{:en:tinkering:labtools:p1140008.jpg?300|}} Or easily measure a capacitor with short leads (eg. unsoldered to make a diagnosis) using alligator clips {{:en:tinkering:labtools:img_3816.jpg?300|}} ===== Enclosure ===== For better handling it, i have designed a 3D printable enclosure for the adapter using [[http://www.freecadweb.org/|FreeCAD]]. {{:en:tinkering:labtools:test_lead_tweezer_adapter_enclosure_preview_thingiverse.jpg?300|}} It's available on [[http://www.thingiverse.com/thing:966401|Thingiverse]]. {{:en:tinkering:labtools:img_4178.jpg?300|}} {{:en:tinkering:labtools:img_4179.jpg?300|}} {{:en:tinkering:labtools:img_4182.jpg?300|}} ===== Resources ===== * [[https://goo.gl/photos/AV2qNmYmenJVXEoh7|Adapter: Full photo album on google+]] * [[https://goo.gl/photos/aMj2SycT5DrLdbEr8|Enclosure: Full photo album on google+]]
