(MIN) and the average (AVG) of current measurements; in the menu, confirms the current se-
lection.
9.
REL/
key: enables the relative measurement (displays the difference between the current
value and the logged value when the key is pressed); in the menu, decreases the current value.
10.
SERIAL/ERASE LOG
key: starts and ends the data transfer to the serial communication port.
In the menu, clears the data contained in the instrument's memory.

MENU
key: allows access to and exit from the menu.
14.
pH/mV-ESC
key when pressed for at least one second, changes the main variable measure-
ment between pH and mV. When the Auto-HOLD function is enabled, slight pressure updates
the measurement. In the menu, cancels the operation in progress without making changes.
15.
°C/°F
key: when the probe is not connected, allows manual modification of the temperature.
When double pressed, changes the unit of measurement for the temperature between degrees
