Use the UP / DOWN keys to set the pH value
of the second buffer solution 2 according to
the temperature.
Note:
In manual temperature compensation, the buffer
temperature set up, otherwise the current buffer
temperature, is displayed.

After successful calibration, the display appears
showing the slope and offset voltage
("Asymmetry"),
e.g.
–
59.1 mV/pH,
ASY 3 mV.
Admissible ranges:
Slope
- 62.0 to - 50.0 mV/pH
ASY
- 45 to + 45 mV

Use the ENTER or M key to go back to the
measuring mode. At the same time, the
"freezing" of the recorder output and the
switching relay is lifted.
