Product Specifications
| SPECIFICATIONS | |
| Display | 18mm (0.7") LCD (Liquid Crystal Display), 3 1/2 digits |
| Function | dB (A & C frequency weighting), Time weighting(Fast, Slow), Max. hold, AC & DC output |
| Measurement Range | 3 ranges, 30 to 130 dB, input signal only. |
| Resolution | 0.1 dB. |
| Accuracy (23 ± 5 ) | 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 250 Hz - ± 1.9 dB, 500 Hz ± 2.5 dB, 125 Hz - ± 2.0 dB ± 1.9 dB, 1 kHz - ± 1.4 dB 2 kHz ± 2.6 dB, 4 kHz ± 3.6 dB, 8 kHz - ± 5.6 dB |
| Frequency | 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. |
| Weighting Network | 31.5 Hz to 8,000 Hz. |
| FrequencyCalibrator | B & K (Bruel & kjaer), multi-fuction acoustic calibrator, model: 4226. |
| Microphone type | Electric condenser microphone. |
| Size of microphone | 1/2 inch standard size. |
| Range selector | 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step, with over & under range indicating. |
Time weighting (Fast & Slow) | Fastt= 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. |
| Calibration | * Build in external calibration VR, easy to calibrate by external screw driver. |
| Output Signal | AC output AC 0.5 Vrms corresponding to each range step. DC output DC 0.3 to 1.3 VDC, 10 mV per dB. Out put impedance - 600 ohm. |
| Output terminal | 3.5 mm phone output terminal is provided for connection with analyzer, level recorder, tape recorder. |
| Operating Temp | 0°C to 50 °C (32 F to 122 F). |
| Operating Humidity | Less than 80% RH |
| Power Supply | 006P DC 9V battery(heavy duty type). |
| Power Consumption | Approx. DC 6mA. |
| Dimension | 255 x 70 x 28 mm (10.0x2.8x1.1 inch). |
| Weight | 280 g/0.62 LB (including battery). |
