Option Description
Slope Limit from
previous cal <=
Set the percent difference between the resulting gain factor and the current
value. Options: 1 to 5% (default = 5%)
Note: This option is only available when "Auto accept results and return online"
is selected.
Slope Limit from factory
cal <=
Set the percent difference between the resulting gain factor and the factory
value. Options: 1 to 10% (default = 10 %)
Note: This option is only available when "Auto accept results and return online"
is selected.
Use Calibration Resistor The calibration check resistor is used during the conductivity calibration
process.
Set the analyzer to return to online mode

the analysis of one/multiple grab sample(s), or stay at the bottle mode dialog box (default).
1. Push <<
to show the sliding menu.
2. Push the SETUP icon.
3. Push BOTTLES.
4. Select the TOC Validation, System Suitability or Grab Sample tab.
5. To have the analyzer return to online mode after the operation is completed, select the Return to

are closed. The pump is off. The lamp is off.
Bottle mode operation
Validate the TOC calibration
Validate the TOC calibration with the default settings or custom settings. A TOC validation can be a
single-point analysis or multi-point analysis. Use the default settings with the packaged standards kits
that use RFID tags on the bottles. Use the custom settings to add bottles or to use less replicates.
The instrument response for the validation standard must have a deviation of less than 15% of the
calibrated response to be accepted.
1. Make sure that the TOC standards are at room temperature.
2. Push << to show the sliding menu.
3. Push BOTTLE MODE, then RUN STANDARDS.
4. Push TOC VALIDATION.
5. Select the default or custom settings. The default setting is a blank bottle and one standard of
500 ppb sucrose. To do a multi-point validation, select the custom settings and enter the
necessary configuration. At least one bottle must be selected.
6. Obey the screen prompts to set the number of repetitions and confirm the sucrose standard
values.
Note: To save the new settings as the default, push SAVE AS DEFAULT.
7. Install the standards in the order shown on the screen.
Note: If the bottle bay door closes too soon, push UNLOCK to open the door.
8. Close the bottle bay door, then push the forward icon.
If bottles have been correctly loaded and the RFID tags can be read, the review test setup dialog
box shows. If not, enter the bottle information as prompted.
9. Push START.
