Temperature coefficient
For dialysate, the temperature-coefficient of the solution to be measured is
2.070%. For special applications this factor can be changed.
Use this function only if you are aware of the consequences. By
using wrong values you will get wrong conductivity values.
You reach this function by calling the menu point
temp.-coeff.
You can
enter the new temperature coefficient via the numeric keyboard and
confirm it with >
ENTER
<. Pressing the OK button transfers the new
temperature coefficient to the program, but it is not used until it is selected
in the parameters menu for Conductivity and Conduc Temperature.
By operating the menu point
conductivity range
you
can choose the correct
range with the arrow-keys. While calibrating the solution should have a
temperature of approximately 25 °C. As soon as the measuring value in the
display is stable the calibration value of the solution can be entered by the
numeric keys and can be confirmed with >ENTER<.
After the calibration, all values relevant for the conductivity measuring will
be indicated once more. By operating the ok-key all data will be saved.
While calibrating the conductivity use only fresh standard solutions. Never
refill used solutions into the storage bottle! Keep the solutions in a cool
place.
