PERISTALTIC PUMP
Peristaltic pumps are self priming. Liquid never contacts the pump components. The titrant tubing
is pressed along the rotating rollers of the pump. The rollers compress the tubing drawing titrant
along and out the titrator tip.
TITRATOR STARTUP
• 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.
• Prepare the electrodes and attach pH sensor and reference electrode to the instrument.
• Calibrate the pH electrode. At least a single point calibration in 8.30 pH buffer is necessary
for titration.
• Place the peristaltic pump tube on the pump. See the “Pump Tube Replacement” section for
the procedure.
• Remove the reagent bottle cap and replace the bottle cap with the tubes. Place the reagent
bottle in the appropriate place on the titrator top.
• Connect the tubes with the peristaltic pump (inlet tube is connected with the reagent bottle,
outlet tube is connected with the dosing tip).
• Purge line.
• Calibrate the pump.
• Select
Low Range
in “Acidity Titration” setup parameter.
• Prepare the sample.
• Run a titration and log sample results.
