Battery Replacement
The VB300 does not lose its stored readings when the battery expires or when the battery is replaced. The data
logging process will however be stopped and cannot be re-started until the battery has been replaced and the
logged data has been downloaded to PC.
The battery life is rated for approx. 1000 hours. If in doubt, replace the battery before logging critical data. Use
only 3.6V lithium batteries. Before replacing the battery, remove the datalogger from the PC.
Note:
When the VB300 is connected to the USB port, its battery discharges at a higher rate than normal. To
conserve battery life, do not leave the VB300 connected to the USB port for a prolonged period of time
.
1. Remove the two Phillips screws identified with the two smaller arrows in the diagram below.
2. Slide the battery compartment cover in the direction of the larger arrow.
3. Replace the battery with one of the same type (3.6V lithium, ½ AA).
4. Close the battery compartment and tighten with the two screws.
WARNING:
Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with
local regulations.
