Calibration
Note
Always check the selected buffer set before calibrating.
From the respective buffer set you can use any 2 buffers in any order.
Note
We recommend to always calibrate with the protective hood screwed on so
the electrode is protected. Use a stand as necessary.
1 Connect the WQL-pH logger (with installed electrode) to a USB
interface of your PC via the USB cable.
2 Keep the buffer solutions ready.
3 In the Device menu, select the menu item, Calibrate.
The calibration window appears.
4 Immerse the logger (with the electrode installed) in the first
buffer solution.
5 Use the Continue button to start the measurement.
