Definition:
The general class of goniometer or device used to support and orient the specimen. If the value of _diffrn_measurement.device is not given, it is implicitly equal to the value of _diffrn_measurement.diffrn_id. Either _diffrn_measurement.device or _diffrn_measurement.id may be used to link to other categories. If the experimental setup admits multiple devices, then _diffrn_measurement.id is used to provide a unique link.Examples:
| '3-circle camera' |
| '4-circle camera' |
| 'kappa-geometry camera' |
| 'oscillation camera' |
| 'precession camera' |
