Opening Metrahit cases

<< < (3/3)

Mechatrommer:
do as giosif's maneuver, ie open up the bottom first, and then at the top, slide in a flat thin object and lift up the top cover, it will pop open, i used paper knife without its holder to do the job (see attached picture, edited from dave's video), a flat screwdriver or the hp repair plastic tools may do the job as well i guess... ps: but dont lift up too far when its open, do it slowly as there are 2 wires connecting from pcb to the back of the cover for the who-knows-what jack hole up there... edit: 2nd attachment (the clips)

No, he does not. The best Video I have found so far is this:

Which basically should have you set anyway, but I've tried and my plastic made frightening crackling noises, so I wondered, wether there is a more elegant version.

You'd be disappointed. I am heavily challenged to actually use a multimeter, I'd never even think of repairing one. Just some visual inspection I intend.

That is an excellent idea as well, as a former bass player I should have some flying around. Somewhere, that is.

My device, when bought used, had a sticker across the lower and upper half gap (no photo made unfortunately) that advised against levering (with a screwdriver). Hence this thread. I was wondering, wether the two front holes in the batterie compartment might have anything to do with it.

But the punchline I'll take away, you have to lever out the front part some way, there is no trick in releasing the snap mechanism in a friedly way. 

Thanks again to all of you!

Here is a nice way to open them: You remove the 4 torx screws. Then you pry the bottom oben with your fingers or a soft piece of plastic.

Now comes the tricky part: Hold the meter with the socket pointing downwards, pry on the gap around the middle of the meter and then smack the rear piece on the table a few times. If done right the upper half "jumps" out of the clamp thingies and the meter is open.

Be careful though: There is a short piece of wire where the power supply socket is connected.
