ELECTING THE MEASUREMENT UNIT
Several measurement units are available for some quantities (temperature, pressure, air
speed, ...). To change the measurement unit of a quantity in a measurement line:
1. Select the desired measurement line using
S
and
T
keys.
2. Press SELECT until the UNIT
command in the command bar is
selected, then select the command
by pressing
F2 .
Note : if the quantity has no meas-
urement unit available for selection
or RECORD and/or LOG functions
are enabled, the command is dis-
abled.
3. Select “ <<< ” ( F1 key) or “ >>> ” ( F3 key) to cyclically scroll
the available measurement units.
4. Press ESC to exit the UNIT command.
If several quantities of the same type (e.g. several temperatures) are shown in different mea-
surement lines, you can set different measurement units for each measurement line.
The measurement unit change affects the display and the immediate print of the measure-
ments (PRINT command). The data already stored in the SD card maintain the meas-
urement units selected at storage.
