Users can select the information that is stored for each titration.
To setup the titration report, follow the procedure below:
• From the main screen, press
. The Data Parameters screen will be displayed.
• Highlight Setup Titration Report and press .
• Mark the fields to be included in the titration report with the “*” symbol. Use the and keys to highlight a field and
/ to toggle the field.
• Press to save the customized report .
Preparing the Sample
• Add 50 to 65 mL of distilled/deionized water to the titration beaker.
• Use a pipette or burette to add 5.0 mL of the sample (0.1M Hydrochloric Acid (HCl)) into the same beaker.
• Slide the stirrer assembly up.
• Place the beaker under the stirrer assembly.
• Lower the stirrer assembly until the electrodes are submersed and the stirrer is close to the bottom of the beaker.
• Adjust the level of the sample solution with distilled/deionized water so that the pH electrode bulb is completely immersed in
the sample solution and the reference junction of the electrode is 5-6 mm below the surface.
Performing a Titration
• From the main screen, press . You will be prompted to enter the analyte size. Enter 5 mL and press . The titrator will
start the analysis.
• At the end of the titration, the message “Titration Completed” will appear on the display with the final concentration of the
analyte in the sample and the equivalence endpoint volume.
