Note:- The pressure dewpoint at the end of the test will be calculated on the recorded system
pressure.
For the majority of applications the system pressure can be left at this default setting, however if the
medical-air system is distributed at a different pressure to that being displayed this should be entered
at this stage.
To enter press the right hand side (Set) icon use the keypad to enter the required value, press the
right arrow to return. The (Reset) button will automatically reset the system pressure back to the
measured pressure.
Press the arrow key to proceed.
With the flow control valve in the closed position
connect to the air supply to be tested. Ensure the
supply hose has non hydroscopic properties to
ensure it will not retain excessive moisture and
effect the result. Fit the appropriate adaptor to
the Tester first and then connect the supply hose
to the adaptor.
A test can be carried out at any pressure between
2 and 10 bar.
Note:- If the unit is over-pressurised it will
automatically
shut
overpressure warning; it will then need to be
returned to the manufacturer for checking and
resetting.
Input pressure will be displayed on the measured
pressure bar graph and the adjacent display.
System pressure will automatically default to this
reading.
The instrument will now commence a 5-minute
purge sequence, during which time an airflow will
be passed through the test port and across the
electronic cells. This clears contaminants from
previous tests and ensures that a representative
sample is being tested.
