Ultrasonic milk analyzer7. pH Calibration.Serve <strong>for</strong> pH meter’s calibration. For this purpose 2 sample buffers are used,shown on the display as Low buffer (<strong>for</strong> example 3.00 pH) and High buffer(<strong>for</strong> example 7.00 pH). Follow the procedure:1. Start the Calibration menu.2. Put the probe in the Low buffer.3. Using the analyzer’s buttons enter the exact buffer value. The following isshown on the display:pH CalibrPut Izopot buffBuf=xx.xxx4. The operator has to enter the buffer’s value, when the probe is in itsisopotential point.After that the display shows:pH CalibrPut Izopot buffBuf=xx.xxxV=x.xxxV SetWhere x.xxxxV is the measured in the probe voltage.5. Press the button Set when the readings stop moving.6. Repeat the procedure with the Next buffer. The following messageappears on the display:pH Calibr OKWhich shows that the calibration procedure was <strong>com</strong>pleted successfully. Thecalibrated device is ready <strong>for</strong> making measurements.7. The device automatically passes in mode pH measuring.8. Check the correctness of the calibration by measuring buffer solution 7.00.8. pH Measuring.<strong>Operation</strong> manual 84/98
