Calibration Message
See Table 4.1 for details of calibration messages.
Slope Value
% slope value.
A value between the programmed minimum % slope value (see
5.3) and 105% is displayed. If the value is outside these limits, check the electrode system.
pH check value.
Displayed as an additional indication of electrode system condition; 7pH is the optimum
