Thanks for the teardown. I own a meter that seems to be a rebrand of yours under the name of Enerdis MT14, bought used for about 85€ shipped. I haven't checked if it is a true RMS model as yours seems to be. The French edition of the user manual doesn't have the schematic. |

I just updated my original post to include a brand table at the bottom based on what I could find out so far, maybe interesting for someone. Your device looks like brand new, it must have been sitting in storage unused, wow. Based on the buttons and the manual headline, it's a branded MP14. True RMS is not present on my unit as well, they added it in the successor products (where they also replaced the leather holster/case by a fluke-style soft silicone holster). [Update: I was wrong about it, it is TRMS, see here] If you ever get the chance to open the back cover, I would love to see some pictures of the inside, the stickers on the PCB could provide more clues about the history of this line of devices. Maybe you got a "mp14/07" label with a serial number on it as well, seemingly not all units have it (or it got lost in some of them) based on the few pictures found online. I'll try to make a high quality scan of the schematic next time I have access to a decent scanner. |

Sure I'll take a few shots of the insides soon. It is in great condition, hardly looks as if it has ever been switched on. I bought a nice Topward dual 60V-3A lab supply from the same seller, to my surprise it came in the original box with polystyrene and crocodile leads. I just checked the seller still has the MT 10, MT 11, MT 13 all in great condition if anyone out here is tempted ? >:D |

Your device from ENERDIS (since 1998 part of Chauvin Arnoux) look like it's been sitting brand new in stock for 30 years. There is virtually no information that can be found online about them, so they seemingly are an absolute rarity. But if anyone else is interested, I would step back, because I already have one device and don't want to be greedy about it :-) ... But maybe the seller has other related things of interest to me. |
