Calibration with 0.1 or 0.01 molar KCl solution
(AutCAL On)
Operation
Note
Impurities must always be prevented from getting into the
calibration solutions.
Pressing cal activates calibration.
Calibration can be exited again by pressing meas. Then,
the cell constant of the last calibration is displayed briefly.
Select the calibration solution used (
CALSoL
). A 0.1 and a
0.01 molar KCl solution are available to choose from.
Press cal to confirm the corresponding solution.
Immerse the clean and dry sensor in the calibration
solution (see also “Clean sensors“, page 19).
Press cal to start calibration. If calibration is not desired,
cancel the process by pressing meas.
During calibration the lower line indicates the tempera-
ture. The automatic drift check checks the stability of
conductivity and temperature. The hourglass indicator
flashes.
When the measured values are stable, the temperature-
compensated table value of the KCl solution is displayed.
The measured conductivity value flashes.
Confirm by pressing cal.
The determined cell constant is displayed for a few
seconds. Then, the meter switches back into the measuring
mode.
