Can I download data from logger after battery died?

Data in USB data loggers is always retrievable by connecting logger to USB port of computer to download data, even after battery was dead.


Do I need to re-program data logger to start new recording after last recording stops?

Multi-use data loggers like Tempod series should be re-configured for new recording after previous recording was stopped, but you could enable Repeat Start during configuration then after current recording stopped, you could start recording immediately by pressing Start button. Please note every time starting a new recording will erase existing data in logger, so always remember to download and save data in advance.


What does the lightening icon on LCD mean?

Some  loggers are shipped to customer with power system off status for power saving purpose, once user connects the logger to USB port, the power system will be activated and lightening icon appears on LCD which means logger starts consuming power, it is a remider for to use the logger ASAP.
