Warning 103—Signal 1 buffer full
Warning 104—Signal 2 buffer full
Status message: Signal 1 buffer full or Signal 2 buffer full
This error could occur if you are using a data collection device, such as an
integrator or ChemStation. If the data collection device goes off line during
a run, signal data will be stored in the 6890 GC signal buffer. The buffer holds
400 Kilobyte of data; if the amount of data exceeds the buffer’s storage limit,
this warning will appear. No new data is stored after the buffer is full.
❐
There is a problem with the PC, the cabling to the PC, or the local network
that links the GC to the PC. Check the PC, cabling, and network.
❐
The PC was turned off without closing the ChemStation instrument
session. The GC collects and stores real-time plot data until the buffer
overflows and the warning appears. Next time, close the instrument
session before turning off the PC so that the GC stops collecting data.
❐
The PC entered power saver mode. When the PC enters power saver mode,
its processor slows down and cannot collect data fast enough for normal
communications, eventually causing the warning to appear. If the PC
stays in power saver mode overnight, for example, there will be an error
on the GC but the ChemStation will show a Ready status. Close and
restart the instrument session, and disable the PC’s power saver feature.
❐
There was a software problem on the PC that stops data collection.
❐
There is a hardware problem in the GC. If the problem persists, contact
Agilent Technologies for service.
