Sensor setup: manually identify a sensor

The StreamSmart Aplet is designed to automatically identify a Fourier

sensor

attached to the StreamSmart 400. In some cases, StreamSmart may fail to identify

a sensor or identify it incorrectly. In this case, you must manually identify the sensor

using the

Sensor Setup

dialog box. Press

and select the

Sensor Setup

option, as shown in Figure 4-1, or press

Figure 4-2 shows the

Sensor Setup

dialog box with accelerometers plugged into

Channels 1 and 2. Suppose that the sensor in Channel 1 is not an accelerometer,

but a force sensor. With Channel 1, highlighted, press

!CHOOS

and select the

appropriate force sensor option. In Figure 4-3, the

0-80 N Force

sensor option

has been selected. Press

$OK#

to make this change effective and return to the

Sensor

Setup

dialog box. Figure 4-4 shows the

Sensor Setup

dialog box with the new

changes. Press

$OK#

to finalize any changes and return to the StreamSmart Aplet.

Figure 4-5 shows the

Numeric

view with the new force sensor in Channel 1.
