Whilst researching the idea behind designing and building a handheld Voltage Source I actually ended up buying an EDC 501-J Programable D.C Voltage Source. However, it was the remote programmable version without the front panel controls, so what better to do than design & build my own front panel and retro fit it to the unit. Complete with LCD, pushbuttons & Arduino powered of course!

This is Part 3 of the repair of my Keithley 2001 7.5 digit Multimeter. Picked up quite cheap I was hoping for an in-depth repair.....and it certainly hasn't disappointed so far! In this video I work on the Display Board, the aim to get it up and running with the main digital board.

Part 1 of the video series: Repair & Modification of a Farnell LT30-2 Bench Power Supply. In this video I repair a fault on Channel 1 of the power supply that meant the 0-30Vdc adjustment wouldn't go below 13Vdc.
