CHAPTER 3

Making Your First Measurement

The indications should be as follows:

• Yellow status indicator flashing every 5 s before starting the measurement

• Steady green status indicator after pressing the Start/Pause pushbutton and during

the measurement (if everything is OK)

• Yellow status indicator flashing every 5 s when you have stopped, saved the

measurement and are ready to do another measurement

• Yellow status indicator flashing slowly, 0.5 s on, 0.5 s off, if you pause the measurement

• Red status indicator flashing rapidly if you encounter an overload condition during the

measurement

4) Use the Start/Pause , Continue , Back-erase and Reset pushbuttons to

control the measurement. The status field at the top of the screen will give short textual

feedback on the pushbutton operation. A visual indication of measurement status is also

displayed on the status line, by way of the Stopped icon , the Running icon and the

Paused icon (Fig.3.4).

5) Toggle between different display parameters, as required, by tapping on each parameter

field (for example LAF90.0 in Fig.3.4) with the stylus and selecting other parameters from

the drop-down lists that appear.

Note: The tabs at the bottom of the screen allow you to choose different ways of

displaying the measurement results:

• The Broadband view shows an instantaneous L

readout, with associated bar graph

and four measurement parameters, followed by two measurement setup parameters.

(The first parameter is displayed in a larger font size for better readability (Fig.3.4.))

• The XL View increases the size of the first parameter readout to a four-digit, full-

screen display (including decimal point)
