Hand-held Analyzer 2250 Light – User Manual

12.2 With Logging Software

You can use the Signal Recording facility together with the Logging Software. You can record

the sound for the whole measurement period or you can record sound for controlled parts of the

measurement. The recordings are attached to the profile as sound markers. The signal recordings

can be controlled by the Manual Event pushbuttons, the Back-erase pushbutton, or an external

trigger signal. You can also control the signal recording using the stylus to mark the interesting

part on the profile.

Note 1: Signal recordings can only be done during measurements.

Note 2: Signal recordings can only be done on projects saved on memory cards (or with

hardware version 4, from a USB memory stick).

12.2.1 Setting up the Analyzer

1) Select a Logging, 1/1 octave, Logging 1/3 octave, or Logging SLM project template. (see

section 3.3.1 for more details on templates.)

2) Depending on your memory device:

• Insert an SD memory card in a SD card slot at the bottom of the analyzer

• If you have hardware versions 1 – 3, you can insert a CF memory card in the CF card

slot at the bottom of the analyzer

• With hardware version 4, you can insert a USB Type A stick at the bottom of the

analyzer

Note: You cannot record the signal on the internal disk.

3) Tap the Main Menu icon and select Explorer from the list of options. Navigate to

the memory card, create a job folder for the measurements and set the default

measurement job/path as described in Chapter 6.

4) Tap the Main Menu icon and select Setup from the list of options. Set all the parameters

as required for the Logging measurement, see Chapter 11.

• Automatic, if you want to start the recording when you start the measurement and stop

when you pause the measurement, and to limit the recording to Maximum Duration, if

Duration Limit is set to On

or Manual Event 2 pushbutton during the measurement

• Exclude Event, if you want to start and stop the recording using the Back-erase
