Setting the Gas Inlet for H

S (GX-2012 Only)

If you are using a separate calibration cylinder for the H

S channel, you may set

which gas inlet that cylinder will use. RKI Instruments, Inc. recommends using a 4-

gas mix cylinder that contains H

S and setting this parameter to GAS 1 (factory

setting).

To change the gas inlet for the H

S channel:

1. Turn on the SDM-2012 with a GX-2012 and establish a connection between

them as described above in "Turning on the SDM-2012 with an Instrument".

The GX-2012 will display the home screen.

2. Press and hold the EDIT ENTER button for 2 seconds. The GX-2012 will

display the Edit Mode screen.

3. Press and release the EDIT ENTER button. The GX-2012 will alternate

between the following screens that show the current gas inlet for H

S along

with the current tested sensors setting. For instructions to change the tested

sensors setting, see “Updating the Tested Sensors Setting” on page 28.
