Replace the logger battery periodically to avoid loosing data, due to the battery becoming low. When a low battery condition is detected, the logger will stop any logging session and will enter a low battery state. In this state any access to the logger will result in the following error:
Before replacing the battery, make sure that the logger is not connected to the computer. If the logger is connected to the computer when the battery is replaced, the low battery condition will not be reset and the logger will remain inoperable. If this situation occurs, disconnect the battery, disconnect the logger from the computer, and connect the battery once more.
When the battery is replaced correctly, the logger status light will flash green five times in rapid succession.
General guidelines as to how long a battery will last is shown in the table below. It is assumed that the logger uses a fresh alkaline battery, the status flash frequency is set to 5 seconds, and the status flash is set to the dimmest setting.
