pH ProLab 3000 7.3 Why calibrate? When do you have to calibrate? Buffer sets for calibration 72 Calibration pH electrodes age. This changes the zero point (asymmetry) and slope of the pH electrode. As a result, an inexact measured value is displayed. Calibration determines the current values of the zero point and slope of the electrode and stores them. Thus, you should calibrate at regular intervals.

The Delete file dialog box pops up. 2 Select the file to be deleted and confirm with [OK]. 3 Confirm the safety query with [OK]. The file is deleted.
ProLab 3000 Maintenance, cleaning, disposal 14 Maintenance, cleaning, disposal 14.1 Maintenance The only maintenance activity required is replacing the batteries. Note For maintenance of the electrodes refer to the relevant operating manuals. Replacing the batteries If the meter stays connected to the power supply while the batteries are being replaced, or if they are replaced within approx. one minute, the date and time will be retained in the meter.
Maintenance, cleaning, disposal ProLab 3000 5 Close the battery compartment (1). 6 Using a screw driver, tighten the screws (2) of the lid of the battery compartment. 7 Switch the meter on with . Note If the date and time are lost, the setting of the date and time is displayed automatically after switching on. Set the date and time (see page 59) CAUTION Make sure that the poles of the batteries are the right way round.

Lists ProLab 3000 Glossary Adjusting To manipulate a measuring system so that the relevant value (e. g. the displayed value) differs as little as possible from the correct value or a value that is regarded as correct, or that the difference remains within the tolerance. Calibration Comparing the value from a measuring system (e. g. the displayed value) to the correct value or a value that is regarded as correct.
ProLab 3000 Lists ORP voltage The ORP is caused by oxidizing or reducing substances dissolved in water if these substances become effective on an electrode surface (e. g. a gold or platinum surface). pH value The pH is a measure of the acidic or basic effect of an aqueous solution. It corresponds to the negative decadic logarithm of the molal hydrogen ions activity divided by the unit of the molality. The practical pH value is the value of a pH measurement.
