Zero Init Data Files

Advanced Operation Manual
This feature applies to digital output only, and is mainly
intended for non- Agilent data systems. It may help systems
that have trouble with non- zero baseline output.
When you turn it On, the GC immediately begins to subtract
the current detector output value(s) from any future values.
For example, if you turn it on when the output is 20 pA, the
GC subtracts 20 pA from the digital output until you turn
Zero Init Data Files Off.
You will not see any change in the GC display, but you will
see the change in the online plot available in the data
system.
To change this setting, press [Config], scroll to Instrument,
then scroll to Zero Init Data Files.
