By analyzing sound waves, it is possible to analyze belt tension non-contactly.
**Features** - Expanded pre-installed unit mass values for belt types. You can display the unit mass value simply by specifying the belt type. - High-sensitivity microphone. Improved microphone sensitivity in the low-frequency range, which is effective for long spans of large belts. - Enhanced data selector function. The number of data selectors that can store input data has increased. - Adoption of graphic LCD. The graphic LCD allows for a significantly larger amount of information to be displayed compared to previous models. - Backlight included. Improved usability for work in dark places. - Other basic specifications: - Automatic cancellation of background noise through auto gain adjustment. - Auto trigger function. - Auto power-off function. - Graphic LCD with backlight.

basic information
【Main Specifications】 ■ Measurement Range: 10Hz to 5,000Hz ■ Power Supply: 2 AA alkaline batteries ■ RoHS Directive: Compliant ■ Weight: Approximately 120g 【Measurement Specifications】 1. Gain Adjustment (Automatic Cancellation of Ambient Noise) Regularly measures the surrounding noise environment from the power input until the "MEASURE" button is pressed, automatically adjusting the microphone sensitivity. After pressing the "MEASURE" button, the microphone sensitivity is fixed. 2. Detection of Vibration Waveform Detects sound waves generated by flicking a stationary belt with fingers using a microphone. 3. Noise Component Removal Automatically removes noise components using an internal filter. 4. Period Measurement Measures the period of each cycle of the input waveform using a period measurement circuit. 5. Signal Processing Measures the fundamental waveform from different vibration waveform patterns established through simulation data processing based on conditions. 6. Frequency Conversion Processing Converts continuous stable waveforms into frequency. 7. Tension Calculation Processing Converts belt tension by inputting the unit weight, width, and span length values of the target belt using a numeric keypad.
