When activating averaging, the He concentration is displayed in square brackets (e.g. [25.7])
if the required number of values for calculating the average is not available.
Send data to USB
activates the sending of measured values to the USB interface.
Partial pressure O
2
is the maximum allowed partial pressure of oxygen used for calculating
MOD.
The
Ref. temp. source
option determines whether ambient temperature (
Ambient
) or defined
temperature (
Defined
) entered in the following
Ref. temperature
parameter is used for
calculating the estimated pressure in the tank (by using plug-in thermometer only).
9.2 Measurement units
Other settings are available in
Menu/Measurement units
. Here the analyzer can be switched
to metric mode (
Metric units
), imperial-units mode (
U.S. units
) or the display of individual
units can be selected separately for individual values (temperature, depth, pressure, volume,
mass). The unit settings do not affect the calculations (with the exception of final rounding),
as the analyzer works in SI units internally.
Notice:
Meters and feet are indicated as units of
depth, though in reality this concerns hydrostatic pressure (pressure at the indicated depth in
seawater).
