Edition 01 – April - Dräger FG7000 Operating Instructions Manual

Operating Instructions Dräger FG7000
The test pressure can be adjusted between 20 and 25,000 mbar for
tightness tests, the stabilization time and the measurement time be-
tween 5 minutes and 6 hours. Optionally available high pressure sen-
sors must be used for pressures exceeding 150 mbar.
The input function begins with the selection buttons behind the values.
"Next" starts the measurement program. During the measurement,
">>/<<" can be used at any time to switch between table and diagram
display.
Pressure built-up: In this phase, the measuring device waits for the test
pressure to build up. "Done" confirms that the test pressure has been
reached.
Stabilization phase: The measuring device waits until the specified sta-
bilization time lapses and then automatically switches to measurement.
The stabilization phase can be ended manually by using "Next".
Measurement: The pressure pattern as well as the starting, end and
differential pressure are recorded during the measurement period. The
selected measurement period can be shortened using "Quit".
Done: After the measurement, the recorded results are available.
