Description
Datalogger Operation
Data Source
Selects the number of bits to be read from the device.
A higher number of bits produces more-precise values, but requires more time
and power.
• Selecting the 8-bit option causes the program to read only the 8 bits stored
in the X, Y, and Z MSB registers.
• Selecting 12 bits for the MMA8652FC reads the 8 MSB bits and the 4 bits
stored in the X, Y, and Z LSB registers.
• Selecting 10 bits for the MMA8653FC reads the 8 MSB bits and the 2 bits
stored in the X, Y, and Z LSB registers.
Sensor Rate
This drop-down list enables you to select the rate at which the accelerometer
acquires data.
Delay Options
No Delay
Disables the delay function.
• 5 sec
• 15 sec
• 30 sec
• 1 min
Sets how long that the device waits, after its start button is pressed, before
data is passed to the NVM.
Note:
The delay options are only available when the “Untethered datalog” has
been selected on the Main Screen.
