Note

The NIR detector is noisier than the UV-Vis detector, so a higher Signal Averaging

Time (Ave time) may need to be set in the NIR. To obtain a constant signal-to-noise

ratio over the entire wavelength range, set a value in the Signal-to-noise field. If

you require a faster scan rate, increase the Data interval or lower the Ave Time.

4. Place the appropriate PTFE reference plate over the sample port.

5. Press the ’Goto’ button to open the ’Goto wavelength’ dialog. Enter ’801’ in the

wavelength field and click OK. The instrument will then drive to 801 nm.

Note

Note the SBW reading in the Status Display dialog.

6. The SBW reading needs to be at approximately 18. This can be adjusted by changing

the NIR Energy level in the Setup page, under the Independent tab. If the reading is

greater than 18, raise the value of the Energy level field. If the SBW is under 18, lower

the energy level. Once the Energy level has been adjusted, you will need select OK in

order to note the change to the SBW reading. Then press the Goto button and again drive

the instrument to 801 nm by entering ’801’ in the wavelength field and pressing OK. This

procedure may need to be repeated in order to reach the required setting. Please note that

each time you adjust the Energy level reading, you must also drive the instrument to

801 nm.
