2 Quick guide
The power supply to the measuring unit can be re-established after the ball valve
is opened and a wait time of at least 15 min is observed.
Monitoring of the carrier gas pressure now takes place with the internal pressure
transducer and analytical computer. The pressure at the analytical computer can
be read on the "Status" screen and fine adjustments can be made when checking
the display value.

Connection values: 5.5 bar ( 10%)
Measuring gas / calibration gas / reference gas
Connection of these gases must take place in the same manner as connection of
the carrier gas.
The input pressure should line in the range between 1.1 – 2.5 bar.
The pressure must be identical for all three inputs. The permissible tolerance is
±10%.
The pressure monitoring takes place with an integrated pressure transducer in a
manner that is similar to that of the carrier gas. The measurements are also availa-
ble at the bottom of the "Status" screen of the analytical computer. The measured
input pressure at the
GC 9300 can be read for pressure equalization of the analysis gas input. If the
pressure compensation takes place for measuring gas, the adjustment is also suit-
able for calibration gas and reference gas.
Column supply pressure and column temperature
Continuous monitoring of the pre-settings for the factory calibration is carried out
by the analytical computer during operation. When the limit values are exceeded,
an error message is issued and no further analysis takes place.
Further process
The "Normal Calib." operating mode must be selected after compensation of the
input pressures. The chromatograph performs a calibration cycle.
The PGC 9300 automatically switches to "Autorun" mode after successful calibra-
tion.
Please read chapter 4.5 Interruption of the carrier gas supply for details about in-
terrupting the carrier gas supply.
