GENERAL TIPS FOR AN ACCURATE MEASUREMENT
The instructions listed below should be carefully followed during testing to ensure
best accuracy.
• Purge the peristaltic pump to have fresh titrant when starting a new analysis or
calibration.
• Calibrate the peristaltic pump before performing an analysis.
• Analyze the wine immediately after the sample is obtained.
PUMP CALIBRATION PROCEDURE
Warning: The calibration of the pump must be performed each time the pump tube, the
reagent bottle or the pH electrode is changed. It is recommended to perform the pump
calibration before each set of measurements.
• Using a clean pipette, fill the 50 mL beaker
up to the 50 mL mark with Mi555-001
Standard.
Note: Failure to use clean pipettes will result
in erroneus readings.
• Place the stir bar in the beaker and put the
beaker in the minititrator top.
• Fill the 20 mL beaker up to the 5 mL mark
with the Mi555-005 Acid Reagent and add
the content to the 50 mL beaker.
• Place the beaker into the beaker holder.
Place the probe holder on the top of the
beaker and secure by turning clockwise.
