Bit 3 - Roll: This bit indicates if the instrument roll angle exceeds the tilt sensor operational range
limits.
Bit 3 Roll
0 Ok, valid data
1 Out of range, invalid data
Bit 2 - Pitch: This bit indicates if the instrument pitch angle exceeds the tilt sensor operational range
limits.
Bit 2 Pitch
0 Ok, valid data
1 Out of range, invalid data
Bit 1 - Scaling: This bit indicates the scaling of the velocity output and depends on the velocity range
setting. If the instrument is set to use the highest ranges the least significant bit is 1 mm/s. For the
lowest range it is 0.1 mm/s. The purpose of varying scale factor is make sure we utilize as much as
we can of the dynamic range that is inherent in the system. This is all transparent if you use the
Vector program to convert to ASCII because the data reported in the ASCII files is in engineering
units. If you develop your own programs to read the binary data files, the variable scaling needs to
be taken into account.
Bit 1 Scaling
0 1 mm/s
1 0.1 mm/s
Bit 0 - Orientation: This bit indicates the orientation of the instrument.
Bit 0 Orientation
0 Up
1 Down
Note: For the Vector the instrument is defined to be in the UP orientation when the communication
cable end of the canister is on the top of the canister, ie when the probe is pointing down.
