Spectral resolution on the instrument is either too low or does not match that set in Acquisition settings.
FIX or WORKAROUND
- Check that Veff is set correctly
- Ensure that resolution and peak shape is suitably tuned for the Mode (Sensitivity, Resolution, or Hi Resolution) using Pusher Offset and Reflectron Grid parameters.
- Confirm that the Resolution field in the Acquisition Settings box is appropriate for the Mode, but also similar to the actual resolution displayed by the instrument.
- Rerun the calibration.
