4. Operation

4.8. EC calibration options

Molar standards
147 µS/cm, 1413 µS/cm, 12.88 mS/cm and 111.8 mS/cm at 25 ˚C
(77 ˚F)
Demal standards
1049 µS/cm, 12.85 mS/cm and 111.31 mS/cm at 25 ˚C (77 ˚F)
NaCl standards
1014.9 µS/cm at 25 ˚C (77 ˚F)
Calibration to X value
Manual re-adjustment of the measured conductivity at any value
of the scale.
The EC readjustment is equivalent to calibration with only one
buffer.

Cell constant introduction
Manual introduction of the cell constant. For example, when the
cell has been calibrated previously in a calibration laboratory.
Theoretical calibration
Selecting "theoretical calibration" the calibration data of the cell
in use are replaced by C=1.000 cm
This step is prior to obtaining a calibration certificate.
Calibration frequency
Select between 1 and 99 days.
The instrument by default is programmed for calibration every 15
days and indicates the remaining time to the new calibration.
Selecting 0 h automatically deactivates the re-calibration
warning.
Important note:
Once the calibration is re-programmed, it will be performed with
the new programming.
