Manual EDM 180
Revision 1.0 29.03.2010 Page 38/61
An faultless device shows the message: SelfTest OK, otherwise: New SelfTest.
Should this error message appear more than once a device error is present which has to be remedied.
The instrument tries five times to execute the self-test successfully, then the message „Fatal Error Please
Check!“ appears. See also chapter 12.
Possible reasons are:
• a fluff which hangs at the inlet nozzle and extends into the laser
• a heavy polluted measuring chamber
• device temperature above 40°C
• a failed laser or another hardware failure (humidity sensor)
Moreover one of the two status LED might shine red. If a failure of the vacuum dryer circuit is present, the
LED “Dryer” shines red. In this case exactly control the correct position / installation of the sample pipe
(see also chapter 6).
After a successful self test the actual measurement starts. After every 6 seconds the measured values
after being refreshed. After about one minute the values will stabilize, because in order to have a stable
display always the moving mean (last 10 measurements) will be displayed.
5.3 Illustration of the measured values
Within stand-by mode the kind of illustration of the measured values can be changed by pressing the keys
[PM Mode] and [+] or [-]. Due to the two-lined display only two measurands can be displayed. Pressing the
key [+] within the operation mode, the measurands of the connected climatic sensors can additionally be
displayed cyclically (see chapter 5.6).
