All calibrations require the following:
Flow meter capable of measuring 200 mL/min and lower with accompanying T-junction
(refer to Figure 18) OR an on-demand regulator (refer to Figure 17)
Tubing with low outgassing properties (such as Viton)
Below are some instructions on how to connect your standard gas to calibrate the gas sensors
on your F-900.
a. If using an On Demand Flow Regulator, directly connect the regulator to the IN
port on the F-900. When using an On Demand-Flow Regulator, the gas is drawn
out of the regulator/cylinder by the pump of the F-900. When the regulator is fully
twisted onto the cylinder, the PSI on the gauge will move. Rotate the regulator
until it is tightly onto the cylinder of gas (clockwise).
i. The regulator can be removed from the cylinder (a small puff of gas will
escape) to be used with other gas cylinders or for storage. To remove the
regulator, twist counter-clockwise.

900 IN port.
b.
If not using an On-Demand Flow Regulator, a T-valve must be used
to
release extra pressure to avoid damaging the F-900.
Always open the
regulator very slowly and allow only 1-2 PSI (6-13 kPa) until the ethylene value
starts to increase on the F-900, reference Figure 18.
