BN-ACCL ACCELEROMETER CALIBRATION
Orient Transmitter unit in the X, Y, and Z directions with respect to Earth’s gravity. This action will introduce 1
G in positive axis direction and -1 G in the negative axis direction. The accelerometer Transmitter/Receiver set
has user-selectable ranges: ±2, ±4, ±8 or ±16 G. The maximum value of each range selection provides a +10 V
output and the minimum value of each range selection provides a -10 V output. When using the ±2 G range, a + 1
G input will provide a +5 V output and a -1 G input will provide a -5 V output, when properly scaled.
The BN-ACCL has a factory default of ±16 G. Use the DIP switches on the side of the BN-ACCL Receiver
Module to set the Transmitter to the desired range. If the range needs to be set to something other than ±16 G,
perform the following steps prior to calibration using Earth’s gravity, as described in the previous paragraph.
