MEANING OF PARAMETERS
P1: This parameter allows to select the measurement type, pH or redox (mV). When setting P1=0
(pH reading with two decimal), please note that the two decimal places are visble only for
pH values below 10, because the display can show up to three digits. However, generally the
precision of pH measurements with one decimal is sufficient in most applications.
