Adjusting The Cell Coefficient - Chauvin Arnoux C 320 Notice De Fonctionnement

REMARK:
When the upper limit of the range is exceeded,
1) In locked range mode: the numerical display remains locked at 1999.
2) In automatic switching mode: the instrument switches to the next higher range.
After a power outage or being switched off and on, the C320 resets to the chosen
range.

ADJUSTING THE CELL COEFFICIENT

We recommend adjusting the cell coefficient using a reference solution in the
same range as the solution to be measured.
Immerse the conductivity cell and the temperature probe in the reference solution.
EXAMPLE: KCl 0.1 mol.L-1, range 0-20mS value 12.97mS at 25°C
(see table: Conductivity of potassium chloride solutions, on page 40).
