Unit setup: manually select units for a sensor
When the StreamSmart Aplet automatically identifies a sensor, it also chooses a
unit of measurement for that sensor. All subsequent readings from that sensor are
shown using the current unit of measurement. Many, but not all, of the probes have
multiple units of measurement available. For sensors that do have multiple units
available, you can change the unit of measurement at any time using the Unit
Setup dialog box. Press
V and select the Unit Setup option to open the Unit
Setup dialog box, or press
B. In the Numeric view, you can simply press $UNIT#.
Figure 4-6 shows the Unit Setup dialog box with a force sensor measuring
Newtons in Channel 1 and an accelerometer measuring G's (G=9.8 m/
s
2
) in
Channel 2. Note that Channel 2 in Figure 4-6 is highlighted. Suppose you wish
the accelerometer to measure in meters per second squared (m/s
2
) instead. Press
!CHOOS and select Accel. (m/s
2
), as shown in Figure 4-7.
