High Pass Filter
- The accelerometer contains an optional high-pass filter which is disabled
by default. The high-pass filter corner frequency is effected by the low pass filter setting. When
enabled, the high pass filter -3 dB point will be equal to the corresponding low pass filter value
as shown in Table 5 below.

4.2 Calibration Configuration
Each node is calibrated at the factory and stores its linear calibration coefficients in nonvolatile
memory. These coefficients are applied by the node when the node is outputting data in
“floating point” format. The coefficients are applied automatically by SensorConnect when the
node is outputting data in signed 16- bit or signed 24- bit formats. For the available data types,
the calibration coefficients are applied as follows:
Float (4 Bytes): Calibration applied by node
Int24 (3 Bytes): G-force = value * slope + offset
Int16 (2 Bytes): G-force = 64 * value * slope + offset
