Connecting the DataFID with the Calibration Gas Bag and the Zero Air Bag
Use the calibration kit (Part No. MX396011) as follows:
1. Connect the regulator to the calibration gas cylinder.
2. If you are using a portable tank of calibration gas, connect the regulator supplied with the
calibration kit.
3. If you are using a large cylinder of calibration gas, you must obtain a high purity regulator.
Be sure to match a regulator with the gas tank fitting. Connect the regulator to the tank of
calibration gas.
NOTE: Do not force the connection. Do not use Teflon tape with CGA fittings. In general, these
fittings are designed for metal to metal sealing. Do not use adapters to connect one CGA fitting
to another type of CGA fitting. If the regulator does not match the outlet on your calibration tank,
contact your specialty gas supplier.
4. Tighten the regulator onto the tank with a wrench. Do not over-tighten.
5. Attach the knurled nut on the gas bag adapter to the regulator. Finger-tighten the fitting.
Figure 32. Gas Bag Adapter
6. Loosen the knurled nut on the reducing union of the bag adapter.
NOTE: Do not remove the nut from the union, as the Teflon ferrules contained inside the nut
may be lost.
7. Insert the tube stub from the gas bag into the knurled nut. Tighten the knurled nut and ensure
the tube stub is secure. If the gas bag is not secure, ensure you have inserted the tube stub far
enough into the knurled nut. Do not over tighten the fitting.
WARNING
Over-tightening the Teflon ferrules will result in damage to the ferrules.
