3. After the readout is complete, you can plot the data. Note that readout speed depends on the method used to connect to the logger and the device being used. Typically, a readout via PC interface cable with the computer will take about six minutes for a full Micro Station (512K of data). -
Page 16: Estimating Battery Life
Do not expose the contents of the battery to water. Estimating battery life Battery life will vary with: • Logging and sampling intervals in use (most important factor) • Number of sensors • Battery type • Operating environment HOBO Micro Station User’s Manual... -
Page 17: Checking Battery Status
It is always recommended that you read out the logger before replacing batteries. If you replace the batteries while the Micro Station is logging, it will stop recording data. The data will not be overwritten, however, until the next launch. -
Page 18: Time Accuracy
Upon launch, the Micro Station’s clock is set in Coordinated Universal Time (UTC), which is determined from the clock on your computer. Once the Micro Station is logging, it will keep fairly accurate time. However, there are three main sources of errors with time reporting. -
Page 19: Logger Memory
The following figure shows the expected run time for several logging intervals based on the total number of bits in place, which is determined by adding together the bits per sample for each sensor measurement parameter in your system. For example, a Micro Station with the following sensors is using 56 total bits. 1 Temperature... - Page 20 Chapter 3: Logger operation At a logging interval of 5 minutes, the memory run time for a Micro Station using 56 bits would be approximately 250 days (based on the following figure). See the sensor’s manual for the number of bits each type of sensor uses.
