I'm glad I got the 453 last time this was up. It comes in a lousy plastic packaging. So I opened it up. Oh my the stink and the rubber feels nasty. The ETL Certification number on the back doesn't seem to apply or I can't find it as applying to these models. The Intertek certification applies to the DDM450B and DDM453B. I found a little crappy voltage probe on home despot with the same ETL certification number. Intertek 3080912 The cables actually seem to be properly rated but they are PVC and nickel plated. 1000V at 80'C according to the stricter Canadian tests, 2000V for the American certifications. Nothing glorious just 18AWG rated but the probes are nice and thickly molded so they should be comfy. They lack any strain relief though. It comes with a super crappy HD 9V battery. It actually has a manual with some actual usable instructions and the english isn't too bad. The meter won't flex when I tried to bend and twist it, but it did groan and squeak a little. But it's so light... I don't expect it to have much inside. Edit: grabbed the new spec sheet from Dawson Tools. It says CE/ETL but leaves off the logo, the 453B is bluetooth enabled and it shows off the ETL logo proudly. DDM453: www.dawsontools.com/datasheets/DDM453_Data_Sheet.pdf DDM453B: http://www.dawsontools.com/datasheets/DDM453B_Data_Sheet.pdf Hmm... I even chased the models I found with the same intertek code, and nothing. It's a cheap but capable meter made by Mastech in China and likely resold under a half dozen names. Little off putting that it's not listed anywhere in the intertek listings, so I think it never made it to the testing and the company says it should meet the requirements, good enough right? This way they can sell their stock carrying the logo and number. Heh Edit2: Upon opening the thing I was pleasantly surprised. It's actually kind of proper and it uses UR listed components. It's also apparently quite easy to hack the controller and make some real improvements. [image] The battery cover screws thread into brass inserts but the body is plastic screws. Here's a link to the walkthrough about the DTM0660L controller: http://www.kerrywong.com/2016/03/19/hacking-dtm0660l-based-multimeters/ Of course modifying your meter voids the warranty but the warranty only applies in the US anyway. So you have to think about whether or not its worth the risk to yourself, the meter, and possibly others if you make dangerous modifications.
