Battery charger
Symptom Action Cause
The charging is stopped
before the battery is
fully charged.
Charger symbol on the
status bar is red.
Disconnect battery
charger. Wait 5
seconds. Reconnect the
battery charger. Look at the charger symbol on the status bar. If it
is red one of the following problems caused the
charging system to stop charging:
-Battery pack temperature is above 60
0
C
-Charging time is longer than 4 hours
-Battery pack voltage during charging is beyond
expected limit. This may happen if one of the
cells in the battery pack is defective or when
there is a connector problem.
- Battery charger voltage cannot supply desired
charging current
- Voltage change ratio on battery pack signals
that the battery is fully charged.
The charging process
does not start. Check the battery
connectors and the
fuses. If the battery pack voltage before charging is
almost nothing the charging system assume that
a battery pack is not connected and will not start
charging. This may happen when the instrument
has not been used for a long time (2-3 months).
The battery charge ratio
shown on display is
incorrect Discharge the
instruments battery (a
suggestion is to use
Data logger). Perform a
full battery charge after
this. The instrument integrates the current to and
from the battery pack and display the remaining
capacity.
This appears typically when the battery pack is
worn and the internal power loss is significant.
Also when the instrument have been OFF for long
time.
Also when you disconnect the battery pack, the
remaining capacity is shown as 0.
The battery voltage displayed in the Main menu
is a direct measurement of the battery voltage,
disregarding calculated remaining capacity, this
may be used to evaluate the battery pack status.
