4 Connecting Calibration Gas
Installing a cylinder of calibration gas is a simple operation. Place the cylinder in the gas cylinder
dock and then turn it clockwise until it is snug.
Once the cylinder is attached, the gauge should immediately give a reading. The reading should be
equal to or greater than 50 psi (approximately 345 kPa or 3.45 bar). If the reading is lower, then the
tank may not have sufficient contents. When it is empty, or calibration cannot be performed due to low
pressure, it should be replaced..
Note:
The AutoRAE Lite is designed to accommodate a 58L cylinder of calibration gas. It can also
accommodate a 34L cylinder, but an adapter sleeve is recommended in order to keep the cylinder
securely docked in the AutoRAE Lite.
5 Air Filter
In order to ensure that fresh air is uncontaminated by dust or other materials, use a filter on the
AutoRAE Lite’s fresh air inlet. The inlet is located on the bottom of the AutoRAE Lite, to the left of
the USB and SD card ports. The filter’s part number is 002-3022-000 (sold in packs of 5, part number
002-3022-005 with 5 metal connectors). Inspect the filter periodically and replace it as necessary.
