8.2.4 Calibration standards

Use two to seven different standard solutions. The standard solutions have to
be selected in either increasing or decreasing order.
Select the unit of the standard solution and measurement result in
the ISE setup/Unit menu.
Standard solution (Std 1 - 7)
Unit [mg/l]
Unit [mol/l]
Unit [mg/kg]
Unit [ppm]
Unit [%]
The measurement precision is also dependent on the selected
standard solutions. Therefore, the selected standard solutions
should cover the value range expected of the subsequent concen-
tration measurement.
If the measured electrode potential is outside the calibrated range,
the [ISEErr] warning is displayed.
8.2.5 Calibration data
The calibration record of the last calibration is to be found under the menu item,
<MENU/ENTER> / Calibration / / Calibration record. To open it, press the
<CAL__> key in the measured value display.
Subsequently, you can transmit the displayed calibration data to the interface,
e. g. to a PC, with <F2>[USB output].
The calibration records of the last calibrations (up to 10) are given in the menu,
<MENU/ENTER>/ ISE / Calibration / Calibration data storage.
