When finished, wait for 15 minutes
until the temperature is constant in
the range 20°C to 30°C.
4
In the ÄKTA ready System Control
module, on the System menu, click
Calibrate. Select Cond_Cal on the
Monitor menu.
5
Read the conductivity value displayed
under Measured value and compare
it with the theoretical value from the
graph opposite at the temperature
of the calibration solution.
•
If the displayed value and the
theoretical value correspond, no
further action is required.
•
If the values differ, proceed with
step 7.
6
Enter the theoretical conductivity
value according to the graph in the
Reference value 1 field.

Click Read value 1. The new cell constant is automatically calculated and
updated.

Testing the temperature sensor
The accuracy of the temperature sensor can be checked using a Temp test tool (
tion 14.4 Ordering information, on page 210
). Temperature testing is normally done once
a year, during preventive maintenance.
