3.3.1 Gas Connections
Before using this instrument, it should be determined if the unit will
be used for pressurized service or vacuum service and low pressure
applications. Inspect the restrictor kit that came with the unit. The kit
consist of two restrictors and a union for 1/4” diameter tubing. Notice
that the two 1-3/4” long, 1/4” diameter tubing are restrictors. It has an
open end and a closed end with a small circular orifice. The restrictor
without the blue sticker is for low pressure and vacuum service. For high
pressure applications (5-50psig), use the restrictor that has a blue sticker
on the body.
For pressurized service (> 5psig) , use the restrictor with the blue
dot and union from the restrictor kit and attach it to the Sample In port.
