Default values are marked in bold.

Calibration

evaluation

The entered calibration data are checked for plausibility by the system. The

check can have the following results:

The entry of calibration values outside the measuring range leads

to a calibration error.

Explanations

Cal - # raw value 1

CarboVis:

-10000,00 ... 0,00 ... 20000,00

NitraVis:

-10000,00 ... 0,00 ... 5000,00

Raw value of the first value pair

(lower concentration).

For single-point calibration, enter 0.

Cal - ref. value 1

CarboVis:

0,00 ... 20000,00

NitraVis:

0,00 ... 5000,00

Reference value of the first value pair

(lower concentration).

For single-point calibration, enter 0.

Cal - # raw value 2

CarboVis:

-10000,00 ... 0,00 ... 20000,00

NitraVis:

-10000,00 ... 0,00 ... 5000,00

Raw value of the second value pair

(higher concentration) or raw value of the

single-point calibration.

Cal - ref. value 2

CarboVis:

0,00 ... 20000,00

NitraVis:

0,00 ... 5000,00

Reference value of the second value pair

(higher concentration) or reference value

of the single-point calibration.

Display

Meaning/actions

Measured

value display

Successful new valid calibration value pairs were entered for

the sensor.

"----"

Calibration value pairs not accepted. Sensor is blocked for

measurement. A log book message is generated.

Causes:



Ascending order not observed.



At least one value is outside the measuring range.
