Technical parameters
Power supply
The device is supplied from an internal Li-ion battery, which is placed under
the rear cover. The battery may be replaced by the producer or an authorized
service provider only.
Battery _________________________________________
Battery model used:
Built-in Li-Ion battery A8200, 3.6V/5200mAh (included)
Operating lifetime relating to a single charge of the Li-ion
rechargeable battery:
Several months to several years according to the device
setting and number of messages sent. Devices with
a CO
2
concentration sensor have a higher battery
consumption and therefore shorter holding time. Follow
the battery status, recharge battery if necessary.
Battery charger __________________________________
Recommended charger type:
Commonly used chargers, such as mobile phone
chargers with a USB type C connector, such as Sunny
SYS 1561-1105
Maximum current from the USB connector:
•
Provided that the datalogger is connected to
the computer and a successful enumeration takes
place, the input current limit will be set to 500mA.
•
If no successful enumeration takes place within
10 s after powering up the device (the device is not
connected to the computer), then the input current limit
is increased to 1500 mA. However, when the input
voltage drops, the current drawn from the connector will
decrease automatically.
Charging time:
Charging time depends on the current battery discharge
level. Since the parasitic heat is generated when
the internal battery is charging, the charging speed for
devices
with internal temperature and/or humidity
measuring is deliberately slowed down to prevent
