Hello Adamcfc101 Please advise if the intermittent error "metering device command failed, draw command aborted" is still occurring on your dual needle multisampler. As Carlos has asked, please also share the following details:
- is this error happening…
Update: FID output signal was very low even when trying to ignite, so we checked the interconnect spring and noticed it was shorter than the ones in the other GCs (not that close to the detector base; dont know if it was always like that or something…
Realize this was a while ago but I just came across it; wrote something similar a while back that processes the data in a given sequence folder - could easily be adapted to run as post-run and post-sequence or also with a specified folder. Hopefully this…
