Conductivity Calibration

[original-reefland]

Question on the conductivity calibration procedure for the Aquacontroller Pro.

Page 31 of my manual, Step 2 states:

Select the appropriate temperature compensation value. Most solutions have a temperature compensation correction factor of 2.0 to 2.5 %/C.

I'm not sure what that means. I have this calibration fluid:

Calitech Conductivity Standard.
447 uS/cm +/- 1.0% @ 25*C


So what value should I enter to the Aquacontroller?

 

[clp]

For salt water is usually 2.1 to 2.2.

I thought the AquaController auto corrected for temperature?

 

[clp]

It does. That is what that temperature compensation factor is for. Salt water has a temperature correction factor of 2.1 to 2.2 %/C.

OK, so the value to enter does not depend on the testing solution? The wording on the instructions made it sound like it might be some number on the packet (which I couldn't find).

 

[clp]

It is just related to the salt water (unknown solution).
