Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
TOC calibration
Calibrate the instrument for TOC measurements with default settings or with custom settings. Use
default settings with packaged standards kits that use RFID tags on the bottles. Use custom settings
for less replicates or less bottles.
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 CALIBRATION.
5. Select default or custom settings.
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. If the bottle bay door closes too soon,
push UNLOCK to open the door.
8. Push START.
9. When the calibration is complete, the results are shown. If a printer is attached, the report can be
sent to a printer. Select the necessary action to complete the calibration.
