weightings and frequency weightings have just been selected,

or those used last time the instrument was operated.

the key to enter.

If data is being logged, logging will continue uninterrupted, but

the display will change to indicate whichever of sound level

(dB) or sound exposure level (Pa

h) was used last time the in-

strument was operated, using whichever of the time weight-

ings, frequency weightings, and exchange rate values (Q) were

used last time.

3. If necessary, press the key again to change from sound

level measurement to sound exposure measurement, or vice

versa.
