15 • Hardware Setup
GAS 1 Tubing
The GAS 1 fittings for up to 10 docking stations can be manifolded together.
Reference Figure 12 for the instructions below.
1. Cut a 3-4” piece of tubing for each GAS 1 fitting on every SDM-E2 except the
last one.
2. Connect the tubing to the GAS 1 fittings on every SDM-E2 except the last one.
3. Insert T-fittings into the tubing so that the remaining two ports on the T-fitting
are perpendicular to the GAS fitting.
4. Cut 6-7” pieces of tubing and connect the T-fittings.
5. Cut one more 6-7” pieces of tubing and connect the GAS 1 fitting of the last
SDM-E2 to the T-fitting from the second to last SDM-E2.
6. Cut 1 piece of tubing long enough for easy access to the calibration cylinder
and connect it to the T-fitting on the first SDM-E2.
GAS 2 Tubing
Reference Figure 13 - Figure 14 for the instructions below.
1. For the purpose of manifolding the GAS 2 fittings of your docking stations,
slightly separate the SDM-E2s into one group of 5 and one group of the
remaining docking stations. If you have 5 or fewer docking stations, you will
only need one manifold. For further explanation of how to properly arrange
your SDM-E2s, see “Instrument Placement for Bump Testing or Calibration” on
page 47.
2. Cut a 3-4” piece of tubing for each GAS 2 fitting on every SDM-E2 except the
last one in each group.
3. Connect the tubing to the GAS 2 fittings on every SDM-E2 except the last one
in each group.
4. Insert T-fittings into the tubing so that the remaining two ports on the T-fitting
are perpendicular to the GAS fitting.
5. Cut 6-7” pieces of tubing and connect the T-fittings.
6. Cut one more 6-7” pieces of tubing and connect the GAS 2 fittings of the last
SDM-E2 in each group to the appropriate T-fittings from the second to last
SDM-E2 in each group.
7. Cut 1 piece of tubing long enough for easy access to the calibration cylinder(s)
and connect them to the T-fittings on the first SDM-E2 in each group.
