Tips for Creating Programs (VWD-3x00)
When creating a program for a VWD-3x00 detector, an AcqOn command can cause a conflict after an Autozero command (or any command that triggers a function that takes some time, such as WavelengthCalibration, WavelegnthVerTest, UpdateLampIntensity) if the time between the two commands is too short. The "Command not accepted" error appears. To avoid conflicts, ensure a sufficient wait time after one of the above commands.
Therefore, add a Wait command before the AcqOn command when creating
