Connecting the Sample Gas
Sample gas connections are made through pipe couplings located on the front of the
monitor unit marked "GAS IN" and "GAS OUT". These couplings are suitable for use with
6 mm O.D. stainless steel or PTFE tubing. If the vent gas is not routed to another test set
or measuring instrument then lower quality tubing may be used on the "GAS OUT" port.
Before operation, the sensor mirror and optical surfaces should be cleaned as described
in section 6.1.

Electrical Connections
Refer to the rear panels of the Series 4000
The instrument requires only a power supply for operation. A 2 meter power cord is
supplied, as standard. A suitable fused power plug, conforming to local electrical safety
regulations, must be connected to the free end of the cord.
IMPORTANT:
Before connecting the instrument to an AC power source make sure that
the power supply is within the limits of the operating voltage specified on
the rear of the unit.
Once the power cord and sample gas connections are made and checked the instrument
is ready for operation.
If indication of %RH relative humidity and remote gas temperature are required, the
remote P.R.T. probe should be placed in the gas flow, and the probe connected to the
connector on the rear of the unit.
Further electrical connections for analog or digital I/O may be required, refer to Section
4.5.
