2.3 Power Options
There are three power options:
•
Lithium-Ion battery: All the instrument functions are available with a charged battery.
•
5 V DC charging adaptor: It supplies power to the instrument and charges the battery at the
same time. It charges the battery when the instrument is on or off.
•
USB mini Type B connection: This charges the battery when the instrument is off and
increases the battery life when the instrument is on.
2.4 Battery
The Device uses 2300mAh Lithium-Ion battery.
WARNING
•
To prevent an explosion or fire, do not short circuit, do not disassemble, and keep it safe
from damage.
•
To prevent an explosion or fire, use only the supplied battery, battery charger and USB cable.
•
To prevent battery leakage or heat generation, only use the battery charger in the
temperature range 0
… 45 °C (32 … 113 °F).
When you set the power on, the battery symbol at the top of the display shows the charging status.
To get more information on the battery, go to the Battery Info Page in the Setting menu.

Operating time
Operation Battery duration
Continuous operation (measure) >18 hours
Continuous operation (measure and source (@12 mA)) >8 hours
These are typical operating times for a new, fully charged Li-Ion battery pack with these settings:
•
Backlight Intensity set to 5 % (Default: 100 %)
•
Backlight Timeout set to 0 (0=Infinite) (Default: 0)
Power saving options : To get the best battery duration, set a low value for the Backlight Intensity
(40 %) and a short Timeout . The maximum operating time without recharging varies depending
on the usage and brightness setting of the display light. Also the generated output current and
the usage of the 24 V transmitter supply affect the maximum operating time.
