Calibration
Note: To abort calibration, you can press meas at any time.
Auto Calibration
( Automatic calibration with specifi cation of the calibration solution
used)
Caution!
• Make sure that the values of the calibration solutions used
correspond exactly to those specifi ed in this manual. If not, the
resulting cell constant will be incorrect.
• When calibrating in a liquid, make sure that the sensor, the
separate temperature probe (if present) and the calibration
solution have the same temperature. Only this ensures that
the cell constant is determined correctly.
1) Select the calibration solution:
• NaCl 0.01 mol/l
• NaCl 0.1 mol/l
• NaCl sat.
• KCl 0.01 mol/l
• KCl 0.1 mol/l
• KCl 1 mol/l
2) Press the Start softkey.
3) Immerse the sensor in the solution and press Continue.
4) Finally, the calibration data record will be displayed.
You can Apply or Discard these values.
Note: Calibration is not possible when the device is connected via USB with
the HandyLab Pilot software.
