4.4 CONDUCTIVITY CALIBRATION

For a correct conductivity calibration the probe

sleeve must be always inserted.

The conductivity calibration menu offers 3 differ-

ent type of calibration: Conductivity, Actual con-

ductivity and Salinity.

Conductivity option allows a 1 point calibration with a standard solution select-

able by the user. This calibration is temperature compensated.

The "Actual conductivity" option allows a custom calibration with a known ac-

tual conductivity solution (not temperature compensated). This option is useful

for calibrating without knowing the temperature effects on readings.

The "Salinity" option allows calibrations with a standard salinity solution.

The 3 ranges are related, if one of them is calibrated, the other two are cali-

brated too.

After choosing the conductivity calibration mode in the main calibration menu,

select the type of calibration with the arrow keys and then press OK.

Conductivity

• Fill a beaker with a standard conductivity solution (see ACCESSORIES sec-

tion).

• Immerse the probe with its sleeve in the solution and wait for the measure

stability.

• The meter shows on the primary display the actual reading and on the second-

ary display the standard value.

• To change the standard value, press CAL. POINT. On display appear the pos-

sible values of standard solutions. The available values are: 84μS/cm, 1413 μS/
