Calibration evaluation
After the calibration, the measuring instrument automatically evaluates
the current status of the electrode. The asymmetry and slope are
evaluated separately. The worst evaluation appears on the display.

1
Connect the pH electrode to the measuring instrument.
2
Keep the buffer solutions ready.
3
Adjust the temperature of the solution and measure the current
temperature if the measurement is made without the use of a
temperature sensor (the TP display indicator is missing from
the display).
