4.5. EC and NaCl measurements

Measurement by stability
The value is fixed on the display when during 6 seconds the
reading variation is less than 1 digit.
During measurement, the measured value appears on the display
from time to time to orient the user.

Continuous measurement

The instrument displays the value obtained by the electrode all
the time.
