1. Sound level range indicator (5 ranges): 30–90dB, 40–100dB, 50–110dB, 60–120dB
and 70–130dB
2. Bar graph shows the current sound level (1dB resolution).
3. Date/time and elapsed time indicator : During integrating this indicator shows the
elapsed time in seconds.
During viewed the peak hold sound level this indicator the “PH”.
During viewed the percentile tile sound level this indicator shows the L:05, L:10,
L:50, L:90 and L:95 parameters.
Others this indicator shows the “year - month - day” or “hour : minute : second”.
4. Leq: Equivalent continuous sound level reading
5. SEL: Sound exposure level reading
6. SPL: Time-weighted sound level reading “Sound Pressure Level”
7. Low-battery indication
8. MAX: Maximum time-weighted sound level reading (blink displayed).
Maximum sound level reading.
9. MIN: Minimum sound level reading.
10. REC : Data records indicator
11. Sound level reading (0.1dB resolution): 30.0 – 130.0dB
12. FULL: Data records full indicator
13. dB: Sound level unit
14. A, C: “A” Frequency weighting or “C” Frequency weighting indicator.
15. IMP: Impulse time weighting indicator
16.
OVER
: Over-range indicator, if this indicator is flashing, to indicate that over-range
data were included in the sound level measurement values for processing.
17. SLOW: “Slow” time weighting indicator
18. FAST: “Fast” time weighting indicator
19.

Press
button again to resume measurement.
21.
: Start and continuous integrating measurement indicator.
22.
UNDER
: Under-range indicator, if this indicator is flashing, to indicate that under –
range data were included in the sound level measurement values for
processing.
