Selecting a Channel’s Units

You can use WaveView to select a channel’s units in one of two ways.

(1) Click in a channel’s Units cell; then select the desired units from the “Select Units” pull-down

list.

(2) Double-click in a channel’s Units cell to cycle through the units. Note that after the mX+b

dialog box appears you must click “OK” to continue cycling.

Note: You can use the mX+b equation to adjust a channel’s scale and offset. You can enter user-defined

units from the mX+b dialog box. An example of using mx + b is provided below, and on the

following page.

After completing channel configuration, you can select the Acquisition Configuration option from

WaveView’s View menu or tool bar. The figure to the right represents the Acquisition Configuration

dialog box. The parameters shown are a result of the values entered below the figure.
Clicking the Close button sets the acquisition parameters as the active parameters.

mX +b, an Example

From the Customize Engineering Units dialog box

(see figure at right), you can enter values for m and b

components of the equation that will be applied to

the data. There is also an entry field that allows you

to enter a label for the new units that may result from

the mX+b calculation.

An example of mX + b equation use follows.
