PHscan30 For better accuracy, we recommend calibrating the tester regularly. DO NOT reuse the buffer solutions after calibration, contaminants solution will affect the calibration and eventually the accuracy of the. measurement. Single Point Calibration Ensure that you have selected 1 point calibration in the setup menu.
Press the Enter key to save and press the Meas key to return to the measurement mode. Temperature Calibration The PHscan30 tester is installed with a built-in temperature sensor for automatic temperature compensation. During the measurement, if the measured temperature reading differs from that of an accurate thermometer, the tester needs to be calibrated.
