功能 (Function)
- dB ( A & C frequency weighting ), Time weighting ( Fast, Slow), Hold, Memory ( Max. & Min. ), Peak hold, AC output, RS232 output.
預設功能 (Meter default Function)
- Range set to auto range.
- Frequency weighting set to A weighting.
- Time weighting set to fast.
測量範圍 (Measurement Range)
- 30 - 130 dB.
解析度 (Resolution)
- 0.1 dB.
範圍選擇 (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.

麥克風尺寸 (Size of microphone)
- Out size, 12.7 mm DIA. ( 0.5 inch).
頻率加權網路 (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.
範圍選擇 (Range selector)
- Auto range : 30 to 130 dB.
