Chapter 1.

3.3 Making a Measurement

3.3.1 What is a Project Template?

A project template contains all the common display settings and measurement setups required

to perform a noise measurement. The template does not contain any measurement data – these

data are saved as individual projects, stored in job folders, see section 6.1.1. The project

templates covered by this manual, are:

• Sound Level Meter (included in BZ-7222 software)

• Frequency Analysis (included in BZ-7223 software)

• Logging (included in BZ-7224 software)

• Enhanced Logging (included in BZ-7225 software)

• Reverberation Time (included in BZ-7227 software)

Note 1: Signal Recording Option BZ-7226 does not contain a specific template – signal

recording options are available in all templates.

Note 2: Tone Assessment Option BZ-7231 does not contain a specific template – tone

assessment options are available in all templates included in BZ-7223/24/25/30.

Note 3: Low Frequency Option BZ-7234 works with all the templates included in

BZ-7222/23/24/25

Note 4: 2-channel Option BZ-7229 (for Type 2270) enables 2-channel operation for all

2-channel templates included in BZ-7222/23/24/25/28 and for Signal Recording Option

BZ-7226 and Low Frequency Option BZ-7234.

If you make any changes to the settings in a project template, an ‘

’ will appear next to the

template name to indicate that the new settings have not been saved. Tap the template name at

the top of the display to open the Template Explorer (or select it from the Main Menu )

and tap the Save icon to save the settings in the current template.
