Slope monitoring
on, [ off ]
If this option is switched on then a check will be made whether the Slope
determined during calibration is within the defined limits. If it is outside them
a corresponding message appears and you can choose whether you will
nevertheless accept the value or whether the previous value is to be re-
tained.
Lower limit
-2.147E+9 ... 2.147E+9
pH: 96.0 %
ISE (+1): 55.0 mV ISE (-1): -61.0 mV

ISE (+4): 12.0 mV ISE (-4): -17.0 mV
Lower limits for the slope.
Upper limit
-2.147E+9 ... 2.147E+9
pH: 101.0 %
ISE (+1): 61.0 mV ISE (-1): -55.0 mV

ISE (+3): 23.0 mV ISE (-3): -16.0 mV
ISE (+4): 17.0 mV ISE (-4): -12.0 mV
Upper limits for the slope.
pH(0) monitoring
on, [ off ]
If this option is switched on then a check will be made whether the elec-
trode zero point
pH(0) determined during the calibration of a pH electrode
is within the defined limits. If it is outside them a corresponding message
