Status
Asymmetry potential (zero)
and slope of the sensor are
still okay.
The sensor should be replaced
soon.
Asymmetry potential and
slope of the sensor have
reached values which no lon-
ger ensure proper calibration.
Replace sensor.
Over 80 % of the calibration
interval has already past.
The calibration interval has
been exceeded.
Check the sensor and its
connections (see also Error
Messages Err 15 and Err 16).
Sensor response time has
increased.
The sensor should be replaced
soon.
To achieve an improvement,
clean or wet the sensor.
Sensor response time has
signifi cantly increased ( > 72 s,
calibration aborted after 120 s)
Replace sensor.
