Lambda power supply and tenma multimeter
« on: May 26, 2013, 07:26:43 pm »
Hi all,

I don't know if I would class myself a "beginner", but I'm more of a hobbyist at the moment (a linux administrator by trade) and am building up a lab, so I guess this is as good a place as any.

I picked up a Lambda LQ-534 power supply for $70 at a surplus place, works perfectly.  It has a voltage and current dial.  What do you think of this model, and do you think the amp/voltage measurements it gives out can be trusted?

I also am considering picking up a tenma bench multimeter for repair cheap.  It's a bench style.  What do you think of this brand?

I must confess I picked up one of those cheap chinese multimeters (a Mastech MY-62) before I watched Dave's review of cheap chinese multimeters.  I can't afford much better right now, though, so I guess this will have to do.  I wish I could pick up a better one but I guess that will just have to wait.

Thanks, and Dave, I particularly enjoy not turning it on, and instead, taking it apart.  My workbench is full of stuff I didn't turn on. :)

Oh, and I picked up one of those Tektronix TDS-340A oscilloscopes.  Any thoughts on this model?  Worst case, it was cheap...

Tenma is basically the name Farnell uses for equipment it rebadges. The Tenma Multimeters seem to be the same as the UNI-T brand and  UNI-T make some great meters for the price. One thing about the Bench Multimeters, if it has an Orange and Grey case (aka the new UNI-T bench meters) then  checkout its size, because these thing are huge. But don’t worry too much because if your running out of space you can always make four legs for that baby and turn it into a dining table.

Cool, thanks.  The multimeter I'm looking at has a bum display but I figure as multimeters go that's probably one of the easiest things to fix.

It's hard kitting up a lab for cheap, but I'm learning, it's very doable as long as you don't go after the latest and greatest.

Thanks for the dining table suggestion. :)  This one doesn't have the orange case, though.
