Connecting Calibration Gas, No SV-3 Attached • 34
If you are connecting multiple SDM-6000s together, it is possible to test GX-6000s
with different gas combinations at the same time. In order to completely calibrate all
GX-6000s, you cannot need more than 3 cylinders since the SDM-6000 only has 3
gas ports on its left side. If testing different GX-6000 combinations at once requires
more than 3 cylinders, you will have to test instruments one at a time and reassign
the gas inlets when you change gases or test the gases common to all instruments at
once and then test additional gases separately. The table below shows some
examples of GX-6000 combinations that could be tested together if you have multiple
SDM-6000s connected together. Up to 10 SDM-6000s can be connected together.
The table below only uses 2 GX-6000s as examples.
