Calibration with any calibration 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.
First confirm any of the 0.1 or 0.01 mol/l KCl solutions
(CALSoL)
by pressing cal.
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.
See the table of your calibration solution for the
conductivity value which belongs to the displayed
measuring temperature.
Set the temperature-compensated conductivity in the
meter using
▲
and
▼
, then confirm it by pressing cal.
The determined cell constant is displayed for a few
seconds. Then, the meter switches back into the measuring
mode.
