1 Connect an IDS conductivity sensor to the meter.
2 In the measured value display, select the conductivity parame-
ter with <M>.
3 Start the calibration with <CAL>.
The cell constant that was calibrated last is displayed.
4 Immerse the IDS conductivity sensor in the control standard
solution, 0.01 mol/l KCI.
5 Start the measurement with <MENU/ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parame-
ter flashes.
6 Wait for the measurement with stability control to be completed
([HOLD][AR]) display or
accept the calibration value with <MENU/ENTER>.
The calibration record is displayed and output to the interface.
7 Switch to the measured value display with <MENU/ENTER>.
