11.8 Power and storage autonomy
Measurement autonomies linked to power are given for a running at 20°C and backlight off. Beware of declining capacity of the battery
or batteries for measurement at low temperature.
• Batteries pack : 3 alkaline batteries 1,5V – LR6/AA type
Autonomy (20°C) : 15H in continuous
• Battery : rechargeable Li-Ion type : 3,7 V – 4400 mAh.
Caution : Li-Ion battery is a delicate element. Take care when manipulating or storing.
Autonomy (20°C) : > 24H in continuous
• Mains supply – charger : type universal USB format – ref : AS-123
PRI :100V – 240V - 60/50Hz – 150 mA
SEC : 5V - 1000mA - 5VA
Autonomy : unlimited, depending on memory capacity of the measurement (see table above).
Note : When a connection to a PC for data transfer, the USB computer delivers a voltage of 5V DC 500mA under. This power supply
has priority over the battery pack or battery that is recharged through this power supply.
34 Technical features
In the event of a reset of the memory by the sound level meter or through the
software LDB200, all the memory is erased.
