The system requires a background spectrum for making measurements with the Affirma Horizontal ATR Lubricant Analysis System. The background should be updated after 2 hours of continuous use.

To perform a background measurement

Install the Pike HATR accessory (sampling plate and baseplate) in the spectrometer sample compartment.
Make sure the sampling plate and ATR crystal are clean and dry. See Clean the ATR crystal in this document for instructions.
In OMNIC Paradigm software Operator mode, select the HATR Setup category and then select the Background HATR workflow.
Follow the instructions in the workflow to complete the background measurement.

When the background measurement is completed, follow the instructions in the next section to run the calibration check.
