TEMP TABLE Compensation Setup
When special temperature compensation is required, you can create your own temperature
table to define the temperature compensation curve.
NOTE: The TEMP TABLE must contain at least two data points (Pt. 1 and Pt. 2) but can have
up to ten. (More points improve temperature compensation accuracy.) Each point
must have a temperature value coordinate (shown as X) and a corresponding ratio
coordinate (shown as Y). Temperature values must be between 0.0 and 200.0°C (or
32.0 and 392.0°F). Each entered temperature value must be different from all others.
Entered ratios, which are unit-less, must be between 0.00 and 99.99 and can have
the same value.
Use this equation to calculate the ratio value for each corresponding temperature
value:
Ratio Value (for each = Cond. Value at Ref. Temp.
corresponding temperature) Cond. Value at Noted Temp.
Example: Suppose the uncompensated or raw conductivity values are 100 mS/cm at a
25°C reference temperature, 120 mS/cm at 50°C, and 70 mS/cm at 15°C. Using this
equation, ratio values for each of the corresponding temperatures are:
For 25°C, ratio value = 100 / 100 or 1.00
For 50°C, ratio value = 100 / 120 or 0.83
For 15°C, ratio value = 100 / 70 or 1.43
The default TEMP TABLE is:
