Sound Pressure Level Measurement

11. Use the SLM / 1/1 / 1/3 key to activate the sound pressure level measurement screen.

12. Use the LEVEL UP/DOWN keys to select the level range. Choose a setting in which

the "OVER" and "UNDER" indications do not appear (the bar graph should register

to about the middle of the range).

13. Press the START/STOP key.

The LED indicator and the mark on the display start to flash, and the takt-max

sound pressure level measurement begins.

When the measurement time set in step 4 has elapsed, the measurement stops auto-

matically. When wishing to terminate the measurement earlier, press the START/

STOP key.

If an overload condition has occurred at least once during the measurement, the

"OVER" indication is shown on the display.

The display reading corresponds to the noise level (sound pressure level).

Using the PAUSE/CONT key, you can pause and resume the level reading and bar

graph display.

14. Press the OPE MODE key to display the takt-max sound pressure level (shown as

Lctm3 and Lctm5 under the sub channel indication).
