calibration (ISE)
1. Select the method which uses the electrode to be calibrated.
2. Connect the electrode system,
114.
3. Press 1 Calibrate electrodes in the Electrode window.
4. Select the ISE electrode from the list.
5. Press 1 to Run, and follow the messages on the display.
For a 3 to 9-point calibration, the E

It is recommended to maintain all your standards at the same
temperature. Then the temperature entered at the start of a
calibration cycle is valid for all your standards.
