in Measurement mode; ‘MEAS’ blinks when in Symmetric mode. The upper alpha-
numerical display shows the measured pH or mV value, while the lower display
shows the temperature value. The indicator “pH” or “mV” at the upper right side of
the display indicates the current measurement mode. (Refer Section 5.5 for
