4.4 Operation

Setup and Operation	Model 6750

f.If the calibration is acceptable, select [OK] or [CANCEL] if not acceptable.

The analyzer is now calibrated and ready for analysis.

4.4 Operation

After proper installation and calibration, the instrument is ready to be placed “ON-LINE” for continuous operation.

Note: For any non–standard or specific operational procedures, please refer to the “INSTALLATION” and “AS–BUILT” drawings in the Appendix or any Addenda that accompanies this manual. If applicable, the Appendix or Addenda will include details on your specific application, which may involve valving, stream sequencing, automatic calibration, etc.

The RUN screen will automatically appear on the screen. It will also appear whenever the computer is rebooted or the power is turned off and back on again. Figure 4-3 shows the RUN screen and identifies the data fields.
