| Display | 52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits. |
| Measurement Range | 30 - 130 dB. |
| Resolution | 0.1 dB. |
| Function | dB (A & C frequency weighting), Time weighting(Fast, Slow), Hold, Memory ( max. & min. ), Peak hold, AC & RS232 output. |
| Accuracy | Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB(31.5 Hz to 8 kHz), then the accuracy of frequency weighting is specified as following: 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 kHz - ± 1.4 dB 2 kHz - ± 2.6 dB, 4 kHz - ± 3.6 dB, 8 kHz - ± 5.6 dB |
| 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= 200 ms, Slow - t = 500 ms, * "Fast" range is simulated the human ear response time weighting. Slow" range is easy to get the average values of vibration sound level. * The "Fast" & "Slow" time weighting range are designed to IEC 61672 class 2 requirement. |
| Range selector | Auto range : 30 to 130 dB. Manual range : 3 range, 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step, with over & under range indicating. |
| Frequency | 31.5 Hz to 8,000 Hz. |
| Microphone type | Electric condenser microphone. |
| Microphone size | 1/2 inch standard size. |
| Calibration VR | Build in external calibration VR, easy to calibrate on 94 dB level by screw driver. |
| Calibrator | B & K (Bruel & kjaer), multi-fuction acoustic calibrator, model : 4226. |
| Operating Temperature | 0 ℃ to 50 ℃ ( 32℉ to 122℉ ). |
| Operating Humidity | Less than 80% RH. |
| Power Supply | 006P DC 9V battery ( Alkaline or heavy duty type ). |
| Weight | 295 g/0.65 LB. |
| Dimension | 268 x 68 x 29 mm ( 10.6 x 2.7 x 1.1 inch). |
