Measurement Aborted
If the measurement is aborted due to low or high pressure conditions, the 973 will heat up the
mirror, restore the measuring head pressure to 100 kPa abs (approximately atmospheric pres-
sure), and stop. Pump back of the stored gas in the internal cylinder can be started by pressing
the
Pump key.
Measurement of Air or Nitrogen (N
2
)
The 973 is equipped with a measuring mode for air or nitrogen. The measured air/nitrogen is not
stored in the internal cylinder and will be pumped to atmosphere through a small vent point in-
ternal to the 973.
Activate the Air/N
2
measurement mode by selecting Hu-
midity Measurement and Air/N2 Mode in the Measuring
Options Menu.
Press the Ok key.
In this measuring mode, only the humidity measurement is
performed, without storing the gas in the internal cylinder.
Press Start .
During measurement, the 973 will pump gas through the
gas connection port, over the measuring head and
through a vent to atmosphere.
Once the humidity value is stable, the instrument beeps
and holds the measured value on the display.
