Connect a Calibration Gas Cylinder


Connect a Calibration Gas Cylinder

The IntelliDoX Enabler Kit includes tubing and quick connect fittings that are appropriate for use with calibration gas cylinders that are approved for use with this product. For best results, BW Technologies recommends that the tubing is between 39 inches (1 meter) and 33 feet (10 meters) in length for calibration gas cylinders.

Before You Begin

1. Read and understand the warnings and cautions in this section
2. Verify that you are in a normal atmosphere (20.9% v/v O2) that is free of hazardous gas.
3. Verify that the end plate is attached and the latch arm is lowered and locked.
4. Verify that the exhaust tubing is connected, and that it is free of defects and obstructions.

The maximum recommended calibration tubing length is 10 meters (33 feet). Use of tubing that is longer than the recommended length may result in inaccurate or failed compliance tests or calibrations

A demand flow regulator must be used with all calibration gas cylinder connections. The module inlet should not be pressurized.

The use of calibration gas cylinders other than those specified by BW Technologies may result in unsafe calibration or possible non-recoverable failure of the equipment, and will invalidate the warranty.

Do not use calibration gas cylinders past their expiration date

Ensure that all calibration gas cylinders are in good condition.

Ensure that all calibration gas cylinders contain enough gas

This equipment uses potentially harmful gas for calibrations. The equipment must be attached to a venting system or be used in a well-ventilated area.

Connecting a Calibration Gas Cylinder

1. Connect a demand flow regulator to the calibration gas cylinder, and then attached the supplied connector with attached 3/16 inch (9.5 millimeter) I.D. tubing to the demand flow regulator
2. Cut 1/8 inch (3.2 millimeter) I.D. tubing to an appropriate length. BW Technologies recommends that the tubing is between 39 inches (1 meter) and 33 feet (10 meters) in length
3. Attach one end of the 1/8 inch (3.2 millimeter) I.D. tubing to the demand flow regulator
4. Insert a quick connect fitting into the free end of the tubing, and then connect it to Inlet 1 on the module
5. If a multi-inlet key is inserted in an individual module or one or more connected modules in a ang, then repeat steps 1, 2, 3 and 4 as necessary until up to 4 cylinders are attached.
6. Configure the gas inlets before using the module. See Configure Gas Inlets on page 9
