5.7 Preparing the transflectance adapter
5.7.1 Adjusting the pathlength of the transflectance adapter to the probe head
When you receive the transflectance adapter with a new instrument:
When you receive your transflectance adpater together with a new NIRFlex N-500 instrument, the
pathlength has already been adjusted to the probe head by the manufacturer.
When you receive the transflectance adapter as additional accessory for an instrument already
installed:
As the probe head dimensions may vary slightly you need to adjust the transflectance adapter to the
probe head when you receive it as additional accessory for an instrument already installed.
A correct adjustment is necessary for the portability of spectra.
To adjust the pathlength of the transflectance adapter to the probe head, the spacer ring 1 mm is
used. The other spacer rings have been manufactured to fit accordingly.
Normally, the transflectance adapter is delivered with the adjustment ring and the spacer ring 1 mm
mounted. If this is the case, proceed with section 5.7.2.
