Calibration Using a Gas Bag

Preparing the Calibration Gas Bag and the
Zero Air Bag
Observe proper handling techniques for all gases! See Compressed
Gases on page 25.
WARNING
Use the calibration kit (Part No. MX390033) as follows:
1. Connect the regulator to the calibration gas cylinder.
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.
If you are using a portable tank of calibration gas,
connect the regulator (Part No. 600649) directly to the
tank.
If you are using a large cylinder of calibration gas, you
must obtain a high purity regulator as specified in
Support Equipment and Consumables on page 28.
Isobutylene in air is usually supplied with a standard
CGA 590 cylinder valve outlet. Obtain a regulator with
the matching fitting. Connect the regulator to the tank of
calibration gas. Tighten the regulator onto the tank with
a wrench. Do not over-tighten.
