4.1.10 Calibration result
Calibration evaluation After calibrating the system automatically evaluates the calibration data
and current state of the sensor. The drift potential and slope are evalu-
ated separately. For a valid calibration, the values have to be within the
following ranges:
Cal.: DOUBLE STD. ADD. (5)
Reference voltage determined
after first standard addition Confirm with
g
.
Add standard to sample Confirm with
g
.
* Wait for a stable measured
value. Confirm with
g
.
The measurement begins.
Cal.: DOUBLE STD. ADD. (5)
Reference voltage determined
after second standard addition Confirm with
g
.
Calibration successful
Conc. (NH4-N)
x mg/l
Slope y mV
Drift voltage z mV
End of DOUBLE STD ADD (5) cal.
The values for Conc. (NH4-N) ,
Slope and Drift voltage are dis-
played.
The calibration is complete. Con-
firm with

.
The display returns to the
measured value display.
