heady 0 Report post Posted May 22, 2006 I think my Sanwa CD800a DMM is not working right. It's less than 6 months old, I think. But it doesn't settle down for resistance and voltage readings. It used to work for current measurement in the past weeks but now it won't even allow current thru the probes. This is my first DMM so apart from the inability to measure current, is the constant changing readings normal for DMM? What do the gurus and EE experts have to recommend for a good and inexpensive DMM? Just to see if I can afford to change it. Share this post Link to post Share on other sites
heady 0 Report post Posted May 23, 2006 I feel like the idiot I am... I opened the DMM and saw that a fuse has blown. Fuse rated 0.5A 250V. Wow, did I get so much current thru the DMM? Maybe I should change my nick to empty-heady? Share this post Link to post Share on other sites

heady 0 Report post Posted June 22, 2006 (edited) thanks stocker. Solution to my problem was a fuse from Sim Lim Tower. I think I will just stick to my Sanwa. Edited June 22, 2006 by heady Share this post Link to post Share on other sites
