... / C Double-weighting Measurement】 The A-weighting simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C-weighting simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience.
❤【Fast and Slow Response Rate Conversion】 The spl meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
❤【Maintain the Maximum Value】Long press the MAX key to lock the maximum value measured during the measurement. Note that db meter does not have data logging and saving capabilities. If there is no operation for 10 minutes, the sound meter will automatically turn off.

【Range&Accuracy】Up to 1%. 0.01pF to 47.000nF (1%+2Digit, 0.2s to 1s).
47.00nF to 47.000uF(1%+1Digit, 0.2s to 2s).
47.00uF to 470.00mF(1 to 3%+1Digit, 0.2s to 30s).
【Capacitance Meter】CE certified professional capacitance meter, battery not included,easy to operate and carry. Large 128*64 LCD can display 5 digit reading with backlight.
【Stable Performance】More stable on reading, (with auto running averaging function, can read pF more stable and accuracy). Reading a 2200uF capacitance only takes ~0.2s.
【New Version Test Leads】Comes with 2 test Clips.
The black pen is connected to the negative pole and the red test lead is connected to the positive pole. Suitable for DIY user and professional engineer usage.
【Application】Digital Capacitance Meter can be used for digital analysis, selection of capacitors, measurement of unknown capacitors, matching capacitors, measuring cable capacitance and etc.capacitor tester, also can be used as external power with mirco USB.
