Measurement Range 35 to 130 dB, 3 ranges: Range 1 - 35 to 80 dB, Range 2 - 50 to 100 dB and Range 3 - 80 to 130 dB, Each range with warning indicator for over & under load. Resolution 0.1dB Measurement Frequency 31.5Hz to 8,000Hz. Frequency Weighting Network Characteristics of “A” frequency weighting network. The “A weighting” characteristic is simulated as “Human Ear Listing” response. Time Weighting Default to “Fast” time weighting characteristics. “Fast time weighting” is simulated the human ear response character Accuracy (23 ±5°C) Characteristics of “ A “ frequency weighting network meet IEC 61672 Class 2. Under 94 dB input signal, the accuracy are : 31.5Hz - ±3.5dB, 63Hz - ±2.5dB, 125Hz - ±2dB 250Hz - ± 1.9dB, 500Hz - ±1.9dB, 1kHz - ±1.4dB 2kHz - ± 2.6dB, 4kHz - ±3.6dB, 8kHz - ±5.6dB Calibrator B & K (Bruel & kjaer), multi-fuction acoustic calibrator Microphone type Electric condenser microphone Size of microphone 1/2 inch standard size Calibration VR Build in external calibration VR, easy to calibrate on 94 dB level by screw driver Data Hold Hold function to freeze the display value 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.
