Calibrating a GX-2009
The following instructions illustrate a calibration on a 4-gas instrument. If your
instrument has less than 4 channels, the screens will look slightly different. A 3-gas or
4-gas cylinder, depending on your instrument configuration, must be used to fully
calibrate the GX-2009 in the docking station.
The PC Controller Program is capable of performing a calibration both manually and
automatically on a GX-2009. When a calibration is performed, the PC Controller
Program performs an air adjust operation on a GX-2009 and then applies calibration
gas to the GX-2009. The PC Controller Program analyzes the calibration results and
determines if the GX-2009 passed the calibration.
To manually calibrate an instrument or instruments:
1. Establish a connection between the SDM-2009, GX-2009, and the PC
Controller program as described in “Connecting Instruments to the PC
Controller Program” on page 36.
2. Verify that all of the calibration parameters are set correctly. See “Setting Up
the Configuration” on page 26 for instructions.
3. Verify that an appropriate cylinder is connected to the GAS fitting of each
SDM-2009 or to the GAS manifold line.
