Making a measurement
Press the Start key to begin recording (on data logging intruments with the VoiceTag
function switched on, the VoiceTag screen will show – press skip to move on without
recording a note).
Your optimus is now measuring and recording noise data for all available functions,
regardless of your selected View, and the red animated Running icon will show in the
top left of the information bar.
The measurement can be paused by pressing the Pause/Stop soft key .
Press once to pause/back erase and twice to stop, or alternatively press and hold for
three seconds to stop. (For Pause & Back Erase, see page 21).
The Pause/Back Erase function is only available if this has been enabled in the
instrument menu.
To stop the measurement, press the Stop key. The instrument will change from
measurement to review mode, and your data is stored and ready to review and
download. For instruments without data logging, only the last recorded measurement
is available for review.
