￭ drift-dependent
The measured value will be applied when the value is stable according to the
drift criterion.
The drift thresholds are preset and cannot be changed:
– pH measurement: 0.028 pH/min
– Potential measurement U/mV: 1.875 mV/min
– Temperature measurement T/°C: 0.974 °C/min
– Oxygen measurement DO 0.24 mg/L/min
For the conductivity, various drift thresholds are stored (depending on the
measuring range):
– 0.005 mS/cm/min in the measuring range up to 16 µS/cm
– 0.5 mS/cm/min in the measuring range from 16 µS/cm to 1 mS/cm
– 10 mS/cm/min in the measuring range from 1 mS/cm
For instruments with two measuring channels, the primary measuring chan-
nel for the fulfillment of the drift criterion has to be selected.
