content: Can you post a few photos of the PCB?Oh, almost forgot: Digitek models also start with "DT" usually, though in this case it's more likely to be a CEM indeed.http://www.digitek.com.hk

content: The 901 II appears to be the same as the Velleman DVM9912, also made by CEM.

content: Quote from: PedroDaGr8 on July 23, 2013, 10:45:00 pmThat's quite surely not a UNI-T (not all red DMMs are made by UNI-T), the PCB clearly says DT-9912A-3 which matches the CEM DT-9912. It's sold under a ton of different names by different rebranders, but various photos also exist where it's clearly labelled as "CEM DT-9912" on the housing, e.g.http://www.industrial-needs.com/technical-gallery/displayimage.php?album=171&pid=2024#top_display_mediahttp://www.warensortiment.de/bedienung/bedienungsanleitung-digital-multimeter-dt-9912.pdfhttp://edura-instruments.de/product_info.php?language=en&info=p172_Digitalmultimeter-DT-9912.htmlUwe.

content: CEM have a particular style that's used on all of their meters - that rotary switch and the font etc. They are the OEM for heaps of different brands (including some Extech models). Quality is pretty decent most of the time. Not fluke quality but not cheap garbage either.
