7.
FUNC/ENTER
key: during normal operation displays the maximum (MAX), the minimum
(MIN) and the average (AVG) of current measurements; in the menu, confirms the current
selection. This updates the display measurement when the
Auto-Hold
function is enabled.
8.
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.
9.

key: allows access to and exit from the menu.
13.
mg/l-%-ESC
key: cyclically changes the main variable measurement between:
•
dissolved oxygen concentration (in mg/l),
•
saturation index (in %),
•
barometric pressure (in mbar).
In the menu, cancels the operation in progress without making changes.
14.
°C/°F
key: when the probe is not connected, allows manual modification of the temperature.
When a probe with temperature sensor is connected, pressing this key twice changes the unit
of measurement from degrees Celsius to Fahrenheit.
