Is this a good multi-meter?






The DMM that you have linked to is a good basic DMM. Get some decent leads for it. This meter measures AC and DC volts, DC current, Ohms, has continuity check, diode check (not for LDs) and transistor gain (Hfe). The manual may be in Chinese, but there is a link for an English one.
 
I agree with Bill...
That is a good Digital Meter to start with...
It has all the features that you will need to build and test Lasers
and Drivers..

I was just looking at that one last night. I'm probably going to grab that one for my self.
I need a non autoranging DMM

I recently bought a Extech nm36 autoranging DMM. It's nice, but really sucks at taking readings from laser drivers when adjusting the pot. The thing just jumps all over the place, and sometime wont ever settle down, unless I turn it off then back on.
 
Another thing I don't understand, is how do I keep the DMM attached AND turn the pot? I can't hold three things at once! Am I supposed to tape it on there?

I use a pair of wires, with alligator clips at both ends.
 
just as said above... get alligator clips you can get packs of them for super cheap from radio shack... and while you are there pick up some supplies to make your own test load... you don't wanna kill that newly aquired LCC :whistle:
 
yeah go for those leads very good for resistors and diodes. there cheaper localy for me there 50 cents and im australian. AND THEY CAN BE ATACHED TO THE MULTIMETER EASILY.
CHEERS
 
Oh yeah, when I asked that question, I thought I was going to be clipping to the IN side for some reason, but, you can get small ones for the LD side?
 
You should be clipping to the 1 Ohm Test Load resistor...
to adjust the current of a Driver...

I'd be using the dead diode I still have on there like I was told I could use....
