Power Consumption Estimates - Kipp & Zonen LOGBOX SE Instruction Manual

6.2 Power consumption estimates

For safe scenario's it is advised to calculate with 50-60% of the mAh capacity as indicated on the battery used. This takes
into account the self-discharge of most batteries and the possibly needed peak current for the GSM modem.
Smart digital instrument need to remain powered all the time as the power-on sequence takes time and most instruments
need to reach a temperature equilibrium. The switched on instruments will have a significant impact on the power
consumption.
A Kipp & Zonen Smart instrument on average uses 8mA on low voltages (5-9V) and 4mA on higher voltages.
