3.2.5.3 Carrying out an ethane analysis
The device is in measuring mode.
1. Make sure the device is drawing in fresh air.
2. Change to the Ethane analysis application.
3. The ethane analysis is generally performed on a bar hole. Use
the localisation probe and a probe hose.
a) Insert the probe into the bar hole.
b) Connect the probe hose to the device.
As soon as the measurement value satises specic conditions
(gas concentration > 1% vol., stable measurement value), the
Take sample symbol appears.
4. Press Take sample. A message appears.
Note:
An ethane analysis takes approximately four minutes. After Esc
is used to cancel the analysis, the detector must be purged (see
Section 3.2.5.2). This purge cycle also takes 4 minutes.
5. Conrm the Take sample? prompt by pressing OK. The gas
sample is taken.
The Add fresh air note appears.
6. Add fresh air.
a) To do so, remove the probe hose from the device.
b) Move away from the bar hole. Note the direction of the wind.
As soon as the gas concentration drops below 50 ppm, the
analysis of the gas sample taken starts automatically. The gas
sample analysis is plotted on the display.
