‘D’ – Enable Fixed Metal Compensation
Syntax:
D
Description:
Compensation refers to programmed offsets that allow system computations to be
accurate, while the system is used in an environment containing metal within
close proximity of the transmitter and receiver. (Generating compensation
requires the use of special fixtures and proprietary software and is usually
performed by a Polhemus technician.)
Purpose:
This command is used to turn on compensation offsets. If a custom calibration has
not been performed by a Polhemus technician at the user location, then enabling
this command will yield no change in the system outputs.
Relatives:
D, d
Default:
The default condition is compensation disabled.
Example:
In most cases, the user is able to locate a test set up where compensation is not
required. If it is required and Polhemus is contracted to perform a calibration, then
the system will be left with compensation enabled. The command to enable
compensation on all active stations is simply:
D
The compensation offsets will now be applied to all position and orientation
measurements.
