Chapter 3

Making your First Measurement

3.1 Introduction

This chapter describes how to make a basic measurement and how to save and document the

results. It assumes you have just received your analyzer and are turning it on for the first time.

If the analyzer has been used before, and the previous user has initiated the multi-user facility,

then the screens that are displayed may not follow the sequence described below. If this is the

case, please refer to section 8.1.6.

Note: A stylus is stored in a holder on the side of the analyzer, see item 15 in Fig.2.1. This can

be used on the touch-sensitive screen to select icons and functions during the procedures that

follow. Alternatively, you can use the various pushbuttons, see items 3 to 11 in Fig.2.1.

The following procedures assume that the measurement microphone and preamplifier have

been mounted as described in Chapter 2 and the analyzer has a fully charged battery, see

section 2.5.1.

3.2 Point and Shoot

Using the following basic procedure you will be able to start using your hand-held analyzer

immediately to make measurements and start the familiarisation process:

1) Switch on by pressing and make sure the Sound Level Meter project template is

selected (see section 3.3.3 for instructions).

2) Check that the data path at the top of the screen displays the correct job/project, (that is,

where you want to save the new data). See section 6.1.1.

3) Set Measurement Mode to Manual and change any setup parameters by tapping the Main

Menu icon and selecting Setup from the drop-down that appears.

4) Press the Start/Pause pushbutton , then monitor the status indicator (traffic light).

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

the measurement.

6) When measurement has finished, press the Save pushbutton to save your data.
