Hello, friends! We have installed a new AAS 280FS device. After installation, the device fails Frequency Diagnostic and Power supply Diagnostic tests according to the SVD software. Please advice, what we can do? Thank you.
Hello Kang: Generally, and aging lamp would be the likely cause of this problem. The average life of the 8453 lamp is 1000 hours. Lamp performance and lifetime may also be affected by physical shock while the lamp is hot, igniting the lamp while it's…
We are trying install OpenLab LTS 01.11 Aug 2022 onto our Windows 10 system; however, the System Preparation Tool states that the Check Pending Reboot step fails even after rebooting the computer.
This is a known issue with the software, but there is…
Thanks for your quick response
but i want to put this limits ( for example 90% to 110%) in my CC editor and in my report called the final result (for example 95%) PASSED and (for example 85%) FAILED. So , how can i translate this limits for different…
Hi all,
I work on a 6470A QQQ. The MS was shut down for maintenance, change of oil of the rough pump, source cleaning, AJS ESI needle replacement and capillary replacement were performed.
Rough vac and high vac values are better than before shutting…
We have intention to upgrade existing Chemstation B version to OpenLab Chemstation C.01.10 version for 6890N and 6890A GC both equipped with TPI inlet (from VAR) and FID.
We are not sure if the upgraded OpenLab CDS able to recognise or support TPI inlet…
Thank you for your advice. Unfortunally not only EM test failed but several others as well. we tried to run it last,first, and even not to run it at all
