4. Check that sample flow rate is between 300 and 1000 SCCM.
CAUTION: FLOW RATES ABOVE 1000 SCCM CAN DAMAGE THE
SENSOR!
5. Power up the system, and test it by repeating the Self-
Diagnostic Test as described in Chapter 4, Section 4.3.5
Note: To achieve the stated accuracy, this unit must be allowed to reach
thermal equilibrium and the sensor must be purged to remove all
traces of water vapor.
6. Purge the sensor for a minimum of 24 hours to remove any
residual water vapor or contaminants.
Note: Purging can be accomplished with sample gas if the gas is dry. If
in doubt, use an inert dry gas connected to the sample in port for
purging.
Following the Self-diagnostic test and sensor purge, if the instrument
is being put into service for the first time or t here has been a significant
change in the vent line pressure, the instrument will require an initial
sensor calibration. This procedure is described in Part II Section 6.6.
If this is not the first time powered up and an initial sensor
calibration is not required, read the entire Section 4 to familiarize yourself
with the operating interface of the instrument, then proceed to Section 4.4
to calibrate the instrument.
