Mettler Toledo PS60 Scale Repair Firmware Backup and Change Scale form LB to LB/ OZ
I have been searching for a decent shipping scale and came across a PS6L on a local marketplace facilitator. I messaged the seller they had a PS6L in the photo but said they sold it but had another one. We met up and when they arrived and it was a Mettler Toledo PS60 and the USB Port on it was a little loose (broken) LOL. Since it was not a PS6L we agreed on a price! Deal was Done. So Now time for a Mettler Toledo PS60 Scale Repair.
Sorry, no Treardown photos this time. See reassembly photo. For Disassembly Just Clipped the wire lock and broke the seal!

Under the Sticker PLCC Chip Philips P89C668HBA PLCC 44 8-bit Flash micro-controller it is in there tight and could not find my extractor or I would have made a backup.
New USB Connector Soldered On to the Mettler Toledo PS60 Main Board And Reinstalled in The Chassis Held In By a Large Standoff, The only Connection is Load Cell Ribbon Cable and Display and USB Cable.
The Mettler Toledo PS60 Scale Repair is it one of the simplest repairs I have done in a long time. This PS60 Has a Nice USB Connector now and should last me years.

I decided to do a Firmware Backup I will Assume this MCU also holds the scales calibration Data.
Scrolling thru the Buffer of the Flash Memory it Looks to be Valid Data
