Prior to carrying out spectrometer signal optimization, the analyzer MUST be in back
purge and offline mode.
6.4.1 Automated Optimization
1. Place the analyzer in back purge mode. This can be done by selecting the Back Purge
field on the Analysis 1 panel and pressing the
↵
key to place an
X
in the box OR by
pressing the F6 key on the keypad.
2. Access the Spectrum panel, navigate to the Optimize Integ Time button and press
↵
. Make sure that the peak height after completion of this operation is ≈ 28000 A/D
counts.
3. Return to the Analysis 1 Panel.
4. Request a Manual Zero by navigating to the Manual Zero button and pressing
↵
.
5. After the Manual Zero is completed, place the analyzer back in Sampling mode by
selecting the Sample field and then pressing
↵
to put an x in the box OR pressing F6
n the analyzer keypad.
6. Place the analyzer back into ONLINE mode by toggling the button on the Analysis 2
panel.
6.4.2 Manual Optimization
1. Place the analyzer in back purge mode. This can be done by selecting the Back Purge
field on the Analysis 1 panel and pressing the
↵
key to place an
X
in the box OR by
pressing the F6 key on the keypad.
2. Access the Spectrum panel.
3. If the peak level is between 25,000 and 28,000 then no adjustment is required at this
time.
4. If adjustment is necessary, optimize the peak signal height to ≈28 ,000 counts. Navigate
to the Set Integ. TIme and press
↵
to display the Integration Period dialog box (Figure
34, Section 4.6). Enter a new integration period in the
New Value
field and press
↵
.
After several seconds, the new raw signal will be displayed. New values for the
Integration Period can be entered until the peak height is 28 000 /- 1000
counts.
5. Once the peak height has been optimized, record the peak height value and the
resulting integration period.
7. Return to the
Analysis 1
Panel.
8. Request a Manual Zero by navigating to the Manual Zero button and pressing
↵
.
