CHAPTER 3

Making Your First Measurement

3.3.2 Switching On

Switch the analyzer on by pressing . The start-up time depends on the state the analyzer was

in when last switched off and it may take up to 2 minutes from a cold start, or up to 10 seconds

if the instrument is already in Standby Mode (that is, from a warm start).

Note: A cold start is a re-boot of the analyzer from ROM. This normally occurs after the

analyzer has been turned off for some time, either by the user or following an automatic power-

down. A warm start takes the analyzer quickly from Standby mode to fully operational without

having to re-boot. (The battery needs to be charged for this to happen, see section 2.5.1.)

3.3.3 Set the Sound Level Meter Project Template

After initialization, the screen shown in Fig.3.1 appears:
