Sample record:
Calibration evaluation After the calibration, the measuring instrument evaluates the current
status of the sensor against the relative slope. The evaluation appears
on the display and in the calibration record. The relative slope has no
effect on the measuring accuracy. Low values indicate that the electro-
lyte will soon be depleted and the sensor will have to be regenerated.
