Page 18: Calibration Mode
Instruction Manual lpha-CON 560 4. Calibration Mode 4.1 About Calibration Calibration should be carried out each time a new electrode is attached to the controller or when you suspect that the controller/electrode is out of calibration. The controller allows you to perform temperature calibration and conductivity calibration. -
Page 19: Calibration
Instruction Manual lpha-CON 560 4.2 Calibration The controller requires one-point calibration. Conductivity calibration is always carried out in the specific measuring range selected for the controller. Make sure, the controller is set to desired measuring range before you enter calibration mode (Refer Section 5.6 for selecting measuring ranges). Select a suitable standard conductivity solution so that its conductivity value is within 10% to 100% of the full scale of the selected measuring range of the controller. - Page 20 Instruction Manual lpha-CON 560 NOTES: The acceptable calibration window is ±40% of the displayed (default) value. For example, if the display is 1000 μS, the values to which it can be adjusted is 600 to 1400 μS. If the conductivity reading of the solution is not within 10% to 100% of the full scale of the selected measuring range, calibration error occurs;...

Page 23: Temperature Settings
Instruction Manual lpha-CON 560 5.3 Temperature Settings Automatic Temperature Compensation (ATC): The conductivity value of a sample is affected by temperature. Use ATC feature of the controller to compensate for conductivity changes when the temperature of the sample or process liquid fluctuates. Connect a separate temperature probe (Pt100/pt1000) to the controller if an integrated conductivity/Temperature probe is not available. - Page 24 Instruction Manual lpha-CON 560 If ATC enabled (ATC On): Selecting temperature offset: The upper display shows the last configured temperature offset value (if any), otherwise the default is zero. The lower display shows currently measured temperature reading (including last configured offset value). LCD shows ‘ATC’ annunciator in lower-right corner.
