TITRATOR STARTUP
This is a general outline of the steps required to make a titration. The following topics are
expanded upon each section that follows.
• Place the instrument on a flat table. Do not place the instrument in direct sun light.
• Connect the power adapter to the instrument.
• Turn the instrument ON using the power switch from the rear panel of the instrument.
• Set up the instrument. See the “Setup Configuration Menu” section for details. Pay attention
to the Acidity Unit.
• Connect the pH sensor and temperature probe to the instrument.
• Calibrate the pH electrode. At least a single point calibration is necessary for titration.
• Place the peristaltic pump tube on the pump (inlet tube is connected with the reagent bottle,
outlet tube is connected with the dosing tip). See the “Pump Tube Replacement” section for
the procedure.
• Remove the reagent bottle cap and replace with the bottle cap with tubes. Place the reagent
bottle in the appropriate place on the titrator top.
• Purge the titrant. Verify titrant is leaving titrant tip.
• Calibrate the pump.
• Prepare the sample.
Note: Different volumes of juice are required for measurement accuracy. See SAMPLE PREPARATION
for details.
• Run a titration and log sample results.
