7. Enter a name for the new calibration protocol, and then press the
Save
button.
These ranges are based on a completely filled 40-mL Vial and no sample flushes. The maximum
number of repetitions that can be selected is 20. Divide the number of reps shown above by 2 for TOC
and TC modes.

Calibrating the Analyzer
To calibrate the Analyzer
1. Select the
Cal/Ver
tab.
2. Press the
Calibrate
button.
3. Select a calibration protocol from the list by touching the screen. If you want to create a new
calibration, follow the previous steps in
“To set up a new calibration” on page 116
4. Press the
Start Cal
button and follow the on-screen prompts. The prompts will vary depending on the
settings you have specified in the selected calibration.
5. After the Analyzer has completed measurements on all standards vials, the
Calibration Summary
screen
displays the following values. (Refer to
• Expected - Indicates the expected concentration of the calibration point.
When Auto Dilution is Off, the expected concentration is the Certified Concentration of the standard.
For reagent water, there is no expected concentration, so the entry is “N/A.”
When Auto Dilution is
On
, the Expected concentration is the concentration of the standard after
dilution. For example, if a 1,000 ppm TOC standard is used in the calibration, and is diluted to
calibrate the Analyzer at 100 ppm, the Expected concentration will be 100 ppm.
• Measured: Indicates the average measured concentration of the standard, using default calibration
constants.
• RSD: Indicates the percent relative standard deviation of the non-rejected measurements of the
standard.
• Adjusted: Indicates the calculated concentration of the standard, using the new calibration
constants from the calibration just completed.
