5. When the flush is complete after about 10 minutes, select the Maintenance tab and press
the Calibrate button.
6. Press the Turbo Cal button.
At this point, the prompts on the Analyzer’s display screen will help guide you through the
calibration process.
7. For the Turbo calibration, you will need to sample from the standards containers and must
use the sipper tube (1/16"-OD tubing with a Valco fitting provided in the Analyzer’s
accessories kit). First, use the 1/4" open-end wrench from the accessories kit to loosen the
Valco nut that connects the stainless steel tubing from the IOS System to the Sample Inlet
port; carefully pull the stainless steel tubing out of the way.
8. Insert the Valco fitting into the Sample Inlet port and tighten with the 1/4" wrench by
turning the nut 1/8 turn past finger-tight.
9. Place the open end of the sipper tube into the bottle containing the TOC calibration
standard (4 ppm KHP) that was purchased from GE Analytical Instruments, and press Next.
10. When prompted, remove the sipper tube from the TOC calibration standard bottle, place it
into the bottle containing the IC calibration standard (as Na
2
CO
3
), and press Next.
11. After the IC calibration standard has been analyzed, the calibration summary screen
displays. You should Apply the calibration if the Analyzer indicates that calibration Passed.
If calibration Failed, press the Cancel button to reject the calibration. Before performing
the calibration procedure again, consult the chapter called “Troubleshooting” on page 195
to determine if there is a problem with the Analyzer.
12. You must verify the Turbo calibration when you are finished. Proceed to “Performing a
Turbo Calibration Verification” on page 222 for instructions.
Performing a Turbo Calibration Verification
Use the verification procedure to confirm that the Analyzer’s current calibration is accurate. Plan
on performing a verification after replacement of consumables, such as the UV lamp, pump tubing,
resin bed, or reagents.
Follow these steps to perform a calibration verification:
1. If the Analyzer is taking measurements, press the Stop Analysis button.
2. If you have an ICR unit, make sure the lever is in the Bypass position.
