  • Page 5: Service

    Manual plus GA-12 2.4. Service Due to the fact that electrochemical cells’ parameters change with time it is necessary to carry out a periodical service connected with either the calibration of the electrochem- ical cells or their replacement. We recommend that service be carried out every 12 months or after the device have worked for 200 hours.

  • Page 12 Manual plus GA-12 Single XL test: The averaged results will be stored. The term XL (extra long) is used for the formation of especially long averages. XL test time can be set via Options second screen or on current screen by the use of the keys: Available times: 10sec, 20sec, 30sec, 1min, 2min, 5min, 10min, 15min, 20min, 30min.
  • Page 13 Manual plus GA-12 If the memory of analyser is full, and no more reports can be stored the following screen is shown when the storage is attempted. The storing of results will be stopped and the instrument returns automatically to the results screen.

  • Page 14: Action Menu

    Manual plus GA-12 function key is pressed during the X2 or X3 test, the measurement is disrupted but it’s result will be stored. During the XL test, its result can be viewed. Pressing the key during displaying the results screen, for a few seconds, the XL test results’ will be shown (averaged for the period of time since the beginning of the test).
  • Page 15 Manual plus GA-12 Pressure test The following screen will appear: The upper displayed value is the currently measured pressure value. The value in the frame is the value stored for a printout or a report. T2 in the right upper corner is the set averaging time. If the period of the time since the beginning of the measurement is shorter than the chosen averaging time, the current av- eraging time of the test will be displayed.
  • Page 16 Manual plus GA-12 Soot test The soot test can be carried out provided that the analyser is being supplied with energy from outside. The efficiency of the pump powered by the inner battery is not enough to carry out the test. Also the heating of the probe holder (necessary when carrying out the soot test) requires that the instrument be powered by the mains adapter.
  • Page 17 Manual plus GA-12 With the use of arrow keys the value taken from the comparative scale should be filled in and confirmed with OK key. It is possible to save three mesurements results ( X) which will be visible in a saved report.
  • Page 18 Manual plus GA-12 After confirmation the first test starts followed by the second one. After the first and the second test summary will provide information about the pressure tightness. Ambient CO test This option is used to measure the ambient CO level. After this option is chosen the user will be asked if he want to start the test.
