content: Hi,Anyone with a spare LCD for a Gossen Metrahit ISO DMM (not sure, but may be the same LCD across several Gossen DMM's) that would be willing to sell, please?I've recently obtained one such multimeter whose LCD is cracked and displaying only part of the text.I've already contacted Gossen, but they are only willing to repair the meter and only if I send it to them in Germany.Thank you!

content: I am not that hopeful either, but I thought I'd try just in case.And, yes, most realistic is finding another otherwise borken meter with a working LCD, but that could take a while.In the meantime, I am exploring the option of building a DYI IR-USB adapter for the meter and get the readings on the computer.And 0xdeadbeef on the forum here has done all the work already:https://www.eevblog.com/forum/testgear/metrahit-usb-ir-diy-interface/I've already ordered the PCB, just need to source the components and the acrylic case (0xdeadbeef provided files for the case as well, but Formulor's prices look on the higher range to me).

content: I am pretty sure this model has it's own LCD entirely. If you look at the analog scale of the AM and PM Metrahit you see the are different. The AMs have a scale up to 30 but with different characters . The PM series has an anlog scale up to 60 so they also don't fit.These LCDs are customized especially for Gossen and are not available for the public.The meter is pretty expensive. You could ask the Gossen service for an estimate if it is just the LCD.

content: Gossen would only help if I send the meter to them for them to replace the LCD and calibrate the meter.The total cost of the service plus shipping didn't make sense to me.Still on the hunt for a broken meter of the same model, so I can take the LCD from that...

content: I realize this topic is rather old, but thought I'd check again if anyone might have such a spare LCD or broken meter they are willing to sell.Thanks!

content: I once bought a Metrahit tester with a broken LCD and the distributor in Spain sourced a replacement LCD, and it was cheap. That was a few years ago, they might have changed the policy. I woukd keep asking to distributors.Roberto EB4EQA
