Siemens Water Technologies/RAPIDLab 248/348 - Bubble in sample error
I have a 248 and have recently been getting either a bubble in sample error or a not sample read error. I did a preventative maintenance (deproteinize/conditioner) and checked all the airline and did a primer and I continue to get the error. Has anyone else had this problem and if so how did you fix it. Advise this member.
PerkinElmer/AAS 800 - Communication error 360
The spectrometer begins to initialize but will not complete process. Then the communication error appears; attempts to reconnect through the diagnostics window failed. A notice about firmware upgrade appears but unable to do this because the download soft key is in grey. Can anyone help? Advise this member.
Varian/AA240FS - AA240FS FG Signal Optimization
After optimizing the lamp using DDI H2O, we take away the water and add one of our samples, then swap over to signal optimization. We constantly receive a red bar and negative value. For the life of us we are unable to obtain a positive value and cyan colored bar through adjustments. What would you suggest? Advise this member.
