HP 5890 error - DAC1?

[chemwipe]

Can anyone in here help me with this error?

FAULT: DAC1 TEST

There was a problem with fluctuating pressure in the inlet, which has since cleared up (my supervisor adjusted a few things on the left side of the instrument, actually not sure if he changed a few parts).

Pressure is now holding, but when you go to start a run, you get the DAC1 error.

Anybody familiar with this?

Thanks.

I went to the technical support section of the Agilent website and did a search for DAC1 and got a few hits. Not sure what options you have on your GC but you might start there.
