°C/°F key

The temperature value measured by the sensor present in the dissolved Oxygen probe is used to cal-
culate the saturation index and the dissolved Oxygen concentration in the liquid being measured.
The key changes the unit of measurement between Centigrade or Fahrenheit.
If the probe is not present, the compensation temperature must be entered manually: to manually
change the value shown in the display lower line, press °C/°F once. The temperature indicated starts
blinking. While the display is blinking, it is possible to change the compensation temperature using
the arrows (

and

). Confirm using ENTER. The display stops blinking, and the temperature

displayed is used for compensation.
If the temperature probe is not present, to change the unit of measurement between °C and °F, it is
necessary to press

twice

the °C/°F key.

Up Arrow

When used in the menu, it increases the current variable value. During measurement, if the tempera-
ture probe is not present, it increases its value.

Down Arrow

When used in the menu, it decreases the current variable value. During measurement, if the tem-
perature probe is not present, it decreases its value.
