Hi, I bought a used Temex LPFRS-01 / LPRO from fluke.l on ebay. Unfortunately the unit is broken and shows the same defect as was mentioned about a year ago on this list: after warm-up it locks for a few seconds, but lock is lost again after a few seconds. The lock output pulls low for a few very short intervals afterwards, but that's it.
I got a refund (but excl. the VAT I had to pay at customs), so it's just a small loss. But of course I want to try to get this thing alive again. In the post last year it was mentioned that these used units suffered from some kind of water damage inside. So I opened up the unit, but it looks clean inside. Just very small signs of surface rust on the screws and connector. Here are some teardown photos I made: http://www.egidy.de/temex_lpfrs_lpro/ I have connected the serial terminal. When using the "M" command for monitoring, the unit returns detailed data. The rb signal level is too low on my unit, see the screenshot at the link above. Was anybody here already able to fix such a unit? Any ideas what to look for or other insights?
