Altimeter — Manual 7.2 Normal Operation
7.2 Normal Operation
Upon switching on the system bus and backup battery circuit (see
also section 7.4) Indu Altimeter first performs initial checks. Next,
it goes into charging mode. In most cases backup battery is already
full and charger will shut off in a few minutes. After this, small green
rectangle will be indicating that backup system is in stand-by.
7.3 Capacity Test
In order to verify capacity of the backup battery, please follow the
following procedure.
1. Run Indu Altimeter on the system bus until the battery is fully
charged – wait until the small green rectangle appears on the
screen. This indicates that battery was fully charged.
2. Disconnect the system bus, so that Altimeter (and perhaps
some other instrument like Indu Airspeed Indicator) is now
running only on backup battery.
The battery symbol must
appear.
3. Start measuring time.
4. If the instrument is still running after 30 minutes, then the
capacity of the backup battery is still sufficient. If you do not
reach 30 minutes, the battery must be replaced.
5. You can stop measuring when you reach 30 minutes.
Indu Altimeter has internal protection, which will disconnect the
battery once the voltage in the battery is critical low. This prevents
permanent damage of the battery.
A completely depleted battery should recharge in about 2.5 hours.
