4.1 pH CALIBRATION PROCEDURES
AUTO Calibration recognizes pH 4.01, pH 7.00 and pH 10.00
buffer solutions for automatic, temperature compensated calibrations.
Any calibration solutions can be used but the pH value will have to be
entered manually. Follow the steps below to accomplish a pH
calibration. Example uses pH 7.00 and pH 4.01 buffers.
