General Tools and Instruments DAF4000 - Manual (Page 14)

Battery economy (stop recording)
This feature is possible by disabling the pressure sensor while the instrument is off. The measurements of pressure and
altitude are only active when the instrument is on.
To turn off the sensor, put one of the three records on
(zero hours).
Comments:
4. If you consult the record and you leave displayed 5 h for example, the next time you switch on the Mini Airflow, it will display 24 h if there
has been a new pressure measurement, this being generated by the internal clock (one measurement per hour).
5. On releasing on 0h, the record will no longer do a measurement each hour (but will retain the current contents) thereby giving you
battery economy.
6. In going back to active record mode (anything other an 0h) the current measurement is stored as the starting time and displayed
under 1h.
10. General reset DAF3300, DAF4000
This mode resets by default all figures and removes the cal bration of the compass. In order to carry out a general reset, switch
off the instrument as normal. Then, to restart, hold the button pressed down. At the moment where all the LCD digits appear (see
opposite), release it, then again hold the button down until off. You can then start up your instrument in the normal way.
