% Slope and pH Check Value – Sensor A
% slope value.
A value between the programmed minimum % slope value (see
Set Min Slope – see
Section 5.3, page 30) and 105 % is displayed. If the value is outside these limits, check
the electrode system.
pH check value (zero point).
Displayed as an additional indication of pH electrode system condition; 7 ph being the
optimum value for glass electrodes and 0 ph for Antimony electrodes.
