Hi Dave. My 9 year old son would literally shit his pants if he was to get an MM from you. Yes he knows of you and impersonates you because he is around me when watching all your vids. Yes i watched them all from the very first one. He always pesters me to play with my MM. This would make his bday super special which just happens to be tomorrow. If you do pick Daniel please sign it for him. We are in Wollongong. Cheers.

Hi Dave. Could be the start of a plastics issue. I worked for a company that produced its own rugged PDAs and vehicle trackers a couple of years ago, and we had to abandon production of one of our products because the plastics moulds had worn to the point that injection moulding was no longer possible. However, with the batch before we hit that point we had noticed that on some units certain parts of the plastics were looser than normal. It could be that your multimeter's moulds are starting to wear out, which will mean either new moulds (cost a packet) or retirement of the product.

I think it's the LCD connection and not the switch. The force is transferred through the front plastic case, not the circuit board. I had a Fluke meter that someone threw out that had a similar problem. When I pressed on the front of the meter the segments would go on and off, similar to the problem with your meter. At first I put some cardboard on the inside of the case to increase pressure on the LCD contacts. That worked somewhat. Later I took it apart and cleaned that conductive rubber strip that went against the LCD glass with alcohol, and that completely solved the problem.

The CAT IV meter would be great to get this piece of history running again. (for context it's a Variotram)

Also slight feedback for the new casing. the posts for the screws which secure the bottom pcb to the front case can be a half beesd**k longer and exhibit these symptoms. had some gripe with the UNI-T DMM because if tongue not at the correct angle when you rotate the knob it goes from continuity to resistance with the knob on the continuity. annoying but does it once in a while and my broke student ass needs a multimeter.

Nah. World is just imperfect. Deal with it. You are trying to find a justification to its imperfectness now. This is a bad psychological phenomenon people tend to be trapped into very often. If you really interesting why the rangeswitch is still so popular then ok. First. Plenty of people are just have a fetish on range switch. Dave for example absolutely love how its feel and mention this in many videos. Second. Marketologists are reactionists and tend not to change anything that sells well. Buttons are more convenient but it is not a killer feature. People wouldn't go and buy only Metrix because of buttons. Also this design is only become viable for cheap multimeters for like 7 years and they are slow adopting it.
