Temperature Compensation
The user can choose from the following options:
Linear - the meter will compensate automatically the conductivity using the following formula:
where:
C
ref
- conductivity at reference temperature
C
i
- measured conductivity (uncompensated)
- compensation coefficient
T - temperature
ref - reference temperature
Non-Linear - recommended for measuring the conductivity of the natural water in accordance with the
compensation table on the next page.
Disabled - the meter will display the conductivity with no temperature compensation.
To set the temperature compensation mode:
• Use or to highlight the Temperature
Compensation option.
• Press and then use or to select
Linear, Non-Linear or Disabled option.
• Press to confirm your selection or press to cancel
operation.
