Temperature None
Relative
Absolute For automatic conversion of temperature units, it
is necessary to know whether the calculated re-
sult is an
absolute temperature
(temperature value on the Celsius scale) or a rel-
ative temperature (temperature difference in
°C). If the result of the calculation not a tempera-
ture,
"none" must be set here.
Unit up to 5 text characters Entry of the unit for temperatures
