why did you need the voltmeter then?
Used it to troubleshoot and identify the 3 h-cards I requested an RMA for. Took a voltmeter to all the cards in the second rig while testing 16 cards one-by-one.
Also used the voltmeter to tune a couple Erupter Blades I have a while back.
Seems like a good geek tool to have in any respectable tool-bag either way.^yup, +1
voltmeter is great for almost any sort of electronics troubleshooting - its the essential first aid kit for electrical issues, along with electrical tape
