AVIATION VIBRATION ANALYZER
a. If DAU power is supplied to the CADU, both the ON and OFF keys of the CADU are active. Placing the DAU
power switch to OFF removes power from DAU circuits and external power to the CADU. Placing the CADU
power switch to OFF removes internal battery power.
b. There are, however, certain conditions under which the CADU will automatically power down such as if the unit is
left unattended for longer than 10 minutes while operating on internal battery power. If the CADU powers down
after the 10 minute period, it can be reactivated by pressing the ON key and the operational process will be at the
same place in the sequence as existed prior to the power down.
If the CADU powers down due to a low battery charge, a
warning message will be displayed the next time the
CADU is turned on.
Another CADU initiated power down occurs when the NiCad battery charge gets low. In order to prevent reversal
of the battery voltage, the CADU automatically powers down.
