8 Calibrating sensors
mazine reference solution with the known turbidity value. To avoid mea-
surement errors, the distance to the vessel wall must not be below the min-
imum distance of 20 mm.
The device suggests the reference value "100.0 NTU" (flashing) for the calibra-
tion of the measuring range (0 to 200 NTU) selected in this example.
✱
Set the exact reference value (in this example 112.0 NTU) using the and
keys.
✱
Wait until the measured value (MEASUREMENT) has stabilized.
✱
Confirm with the key.
The values determined for the zero point comparison and the slope deviation
from the factory calibration along with the corrected measured value are dis-
played:
✱
Now reinstall the sensor in the process.
✱
Use the key to apply the calibration or the key to reject the calibra-
tion.
The device returns to measurement mode.
NOTE
The calibration process can be interrupted at any time (e.g. in the event of
fault messages from the device) with the
key and then restarted
