Greg007 Posted January 14, 2021 Share Posted January 14, 2021 This is my first post, I heartily treat all users, :-) Spectrophotometr Hach DR 3900 - hangs on startup. I do not have a service manual - maybe someone has? I replaced the lithium battery on PCB and pressed the restart button - no change. Any suggestions?

Regards When I used to service/repair instrumentation as part of my business I could put up with inadequate initial fault reports since I was being paid to fix things. Here at SF we are not paid. Another member here tried to be helpful (+1) as the user manual contains troubleshooting advice and does indeed list and offer advice on similar circumstances. So how about a proper fault report, starting with Hs this machine ever worked ? If so when and how did it go wrong ? What have you tried apart from battery replacement? Have you for instance tried any of the troubleshooting proceedures listed in the manual ? Link to comment Share on other sites More sharing options...
Greg007 Posted January 14, 2021 Author Share Posted January 14, 2021 I guess I got misunderstood, sorry for my English. I didn't mean that StringJunky didn't help me, just that there is nothing in the user manual about a crash at startup - Section 8 Troubleshooting. The spectrophotometer worked for several years and it happened once that it crashed (for no apparent reason), but after switching it on / off several times, it started working. Now it freezes always.
