Note: This table is as shown on the screen. The gray areas must be entered.
Set the reference temperature in the Temp. comp. screen (default: 25.0°C).
Input concentration values in the Solution screen.
The values must be entered in ascending order from Solution (Min.) to Solution (Max.). Solution
(Min.) and Solution (Max.) must be entered.
Input temperatures for compensation in the Temp. ranges screen.
Input the conductivity values* at respective temperatures in the Solution (Min.) screen and those
in the Solution (Max.) screen. Input other values, if any, in the Solution n screen.
*: Enter the precompensated conductivity.
All cells of two user-dened matrixes are blank as a default. If any cells are not blank, clear them.
After entering all values, select “Check values?” to verify that there is no error.
This function checks if the matrix is consistently incremental or decremental. If any error is found,
its location is specied.
If there is no error, the matrix is compensated linearly and the blanks of the table (if any) are lled.
If some areas are left empty without running “Check values?”, a 1st/2nd comp. matrix error will be
issued.
