7.2.4 Calibration standards
Use two to seven different standard solutions. The standard solutions have to
be selected in either increasing or decreasing order.
7.2.5 Calibration data
Displaying the cali-
bration data
The calibration record of the last calibration is available in the menu Calibration
/ Calibration record. To open it in the measured value display, press the
<CAL_> key.
The calibration records of the last 10 calibrations are available in the menu Cali-
bration / Calibration data storage / Display. To open the Calibration menu in the
measured value display, press the <ENTER> key.
Select the unit of the standard solution and measurement result in
the ISE setup/Unit menu.
Standard solution (Std 1 - 7) Values
Unit [mg/l] 0.010 ... 500,000
Unit [mol/l] 0.100 ... 5.000 µmol/l
10.00 ... 5.000 mmol/l
Unit [mg/kg] 0.010 ... 500.000
Unit [ppm] 0.010 ... 500.000
Unit [%] 0.001 ... 50.000
The measurement precision is also dependent on the selected
standard solutions. Therefore, the selected standard solutions
should cover the value range expected of the following concentra-
tion measurement.
If the measured electrode potential is outside the calibrated range,
the [ISEErr] warning is displayed.
The calibration record is automatically transmitted to the interface
after calibrating.
