Aligning the HATR
Make sure that the sample trough or the flat sampling plate and, if applicable, the pressure
clamp are properly mounted on the base assembly before aligning the HATR.
1.
In Spectrum software, select
Monitor
from the Measurement menu.
The Live tab is displayed.
2.
Record the energy throughput of the HATR.
3.
Compare this value with the value for the energy throughput of the open beam
(recorded at the beginning of the installation procedure – Step 4 on page 11).
If you did not record the value, remove the HATR from the spectrometer and then
measure the value.
If you do not observe an energy throughput, or if you are aligning your accessory for
the first time, continue at Step 4.
If you do observe an energy throughput, and your accessory has been aligned
previously, continue at Step 15.
