| Measurement Type | SPL : Sound pressure level; Dose: test noise exposure |
| Measurement Range | SPL: Auto 35 to 130 dB.; Dose: 70 to 130dB |
| Resolution | 0.1 dB. |
| Function | dB ( A & C frequency weighting ); Time weighting ( Fast, Slow ); Data hold; Record ( Max., Min. ). |
| Accuracy | Characteristics of " A " frequency weighting network meet IEC 61672 class 2.; Under 94 dB input signal, the accuracy are : 31.5 Hz ± 3.5 dB; 63 Hz ± 2.5 dB; 125 Hz ± 2.0 dB; 250 Hz ± 1.9 dB; 500 Hz ± 1.9 dB; 1 K Hz ± 1.4 dB; 2 K Hz ± 2.6 dB; 4 K Hz ± 3.6 dB; 8 K Hz ± 5.6 dB; Remark : The above spec. are tested under the environment RF Field Strength less than 3 V/M & frequency less than 30 MHz only. |
| Frequency Weighting Network | Characteristics of A & C.; A weighting : The characteristic is simulated as "Human Ear Listing" response. Typical, if making the environmental sound level measurement, always select to A weighting.; C weighting; The characteristic is near the "FLAT" response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment. |
| Time weighting | Fast - t = 125 ms; * "Fast" range is simulated the human ear response time weighting.; Slow - t = 1 s; * "Slow" range is easy to get the average values of vibration sound level. |
| Data hold | Freeze the display reading. |
| Frequency | 31.5 to 8,000 Hz. |
| Microphone type | Electric condenser microphone. |
| Microphone size | Out size, 12.7 mm DIA. ( 1/2 inch) |
| Calibration VR | Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.; * Calibrated via external SOUND CALIBRATOR( SC-941, SC-942, optional ). |
| Calibrator | B & K (Bruel & kjaer), MULTIFUNCTION ACOUSTIC CALIBRATOR Type 4226. |
| Advanced setting | * Set clock time (Year/Month/Date,Hour/Minute/ Second); * Set sampling time; * Auto power OFF management; * Set Criterion level in dB; * Set Threshold in dB; * Set Exchange rate in dB; * Check Memory space.; * Set Clear Memory |
| Over Indication | Show " - - - - ". |
| Memory Recall | Maximum & Minimum value. |
| Sampling Time of Display | Approx. 1 second. |
| Data Output | RS 232/USB PC computer interface.; * Connect the optional RS232 cable,UPCB-02 will get; the RS232 plug.; * Connect the optional USB cable, USB-01 will get the; 63 Hz ± 2.5 dB USB plug. |
