NOTE:
The following instructions can also be applied to the AIR fitting if you
are using a zero air cylinder and a humidifier tube to perform a WET air
adjustment.
1.
Connect a 6 inch humidifier tube to the GAS 2 fitting on the back of each
SDM-2012.
2.
Insert the smaller T-fittings into the open end of every humidifier tube except
the last one so that the remaining two ports on the T-fitting are perpendicular to
the GAS fitting.
3.
Connect the last humidifier tube directly to the last T-fitting.
4.
Cut 6-7” pieces of 3/16 inch tubing and connect the remaining T-fittings.
5.
Cut a piece of 3/16 inch tubing long enough for easy access to the calibration
cylinders and connect them to the T-fitting on the first SDM-2012.
