CEMB USA N300 - Manual (Page 10)

1 - 4 General description
Battery
The N300 instrument is equipped with an integral rechargeable lithium battery, offering a
battery life of more than ten hours under normal operating conditions.
The battery status is indicated by an icon in the upper right hand corner of the screen.
-
battery fully charged
- battery partly charged
- battery almost flat (battery life remaining when this appears is approx. one
hour)
-
battery flat: recharge within 5 minutes
If the battery is flat and the instrument is not recharged within 5 minutes it will switch off.
This would interrupt any active measurements not yet saved.
When the battery charger is connected the display lights up briefly indicating the
connection, even when the instrument is switched off.
The battery icon remains animated when the instrument is recharging, progressively filling
up. When charged, the animation stops and the ‘battery fully charged’ icon is shown.
Warning
When connecting the battery charger, first insert the connector into the relevant
socket on the N300 instrument; only plug it into the power supply socket when this
has been done.
When recharged, unplug the battery charger from the power supply socket before
removing the connector from the instrument.
Warning:
We strongly recommend recharging the instrument when switched off; as charging
takes less than five hours, avoid leaving the battery connected for an excessively
long period of time (maximum 12 hours).
Warning:
The lithium battery withstands frequent charging-discharging cycles easily, even on
a daily basis, however allowing it to run out completely can damage it. For this
reason we recommend it is charged at least once every three months, even when
not used for long periods of time.
Note:
As the display backlighting consumes the most power, it switches off automatically
after a certain period of time (settable) has passed without pressing any key.
Pressing any key (excluding )
will reactivate it.
