Pressing on/off switches the meter on or off. When the
on/off
meter is switched off, one of the Sensoface
tors is visible in the display. After power-on, the meter au-
tomatically performs a self test and checks which tempera-
ture probe is connected. After that it automatically goes to
pH measuring mode.
The meter can also be switched on with meas. However,
Note
in this case only a short test is performed and the tempera-
ture probe is not determined. The meter assumes that the
last temperature probe determined is used.
Pressing meas selects the desired measured variable (pH
meas
or mV) for the main display.
Pressing cal starts calibration. With calibration the meter
cal
is adjusted to the electrode. You can choose between one,
two or three-point calibration either using Calimatic
matic buffer recognition or with manual buffer entry.
