Page 9: Overview
Provides an additional explanation. Indicates a location for further reference. Indicates a setting restriction. Indicates that you must check before usage. 6－2. EPS-02Sv2 Features ＊ Measurement sensor is detected from the image for recognizing the measurement location The measurement object and measurement sensor are captured by a camera, and the measurement sensor is found within the image for identifying the measurement location. -
Page 10: 6－3.Measurement Principle
6.Overview 6－3. Measurement Principle The EPS-02Sv2 system performs two main operations for enabling visualization of the sound. First, it performs image recognition that identifies the measurement sensor location from the recording image. Second, it provides a color-coded distribution on the image indicating the strength of the signals detected by the measurement sensor. -
Page 11: System Configuration Diagram
The spectrum analyzer is connected to the PC using the supplied LAN cable. Support is provided for some spectrum analyzers described in [11－3.Supported Spectrum Analyzers] on page 36. Please consult with NoiseKen for use of spectrum analyzers that are not supported. -
Page 12: 7－2.Functions Of Each Device
By using the GAIN changeover switch above the OUTPUT terminal, signals are amplified to 20 dB. For the EPS-02Sv2, the switch must be set to 0 dB (default). Since the spectrum analyzer is highly sensitive, amplified signals are usually not needed. -
Page 13: Preparation
8－1. System Backup NoiseKen provides an optional service (additional charges apply) for installing the EPS-02Sv2 program in your PC before providing the program, but if the program is erased, install it from the supplied DVD. -

Click Other Settings dialog box (1) Color Space / Compression The color space / compression of the camera can be changed. -
Page 18: Image Recognition Setting
9.Operation Procedure Image Recognition Setting Adjust the three parameters, Hue, Saturation, and Value, in the Image Processing Setting so that the color of the sound pressure sensor can be recognized. The binarized image on the right side can be changed by moving the slider of each parameter. Hue: Sets the hue, such as red, blue, or yellow Saturation: Sets the intensity and purity of a hue Value: Sets the lightness of a color. -
Page 19: 9－3.Communication Settings
If the Equipment Name list is blank, no spectrum analyzer driver may exist. Check to see that spectrum analyzer drivers (*.sads) are stored in the folder where the EPS-02Sv2 executable file is stored (C:¥Program Files (x86)¥NoiseKen¥EPS-02Sv2, under normal conditions). -

Page 22: Image Division Size
9.Operation Procedure Image Division Size Set the division size by which a camera image of 640 × 480 pixels is divided. The image division size can be selected from 10 pixels (H: 64 × V: 48 squares), 16 pixels (H: 40 × V: 30 squares), 20 pixels (H: 32 ×... -
Page 23: Measurement Time Setting
9.Operation Procedure How to store spectrum data at the same measurement point (the same square of the grid) can be selected from SINGLE, FREE RUN, PEAK HOLD, or MAX HOLD. SINGLE Performs measurement only one time. FREE RUN Always overwrites the data. Compares the maximum values of the spectrum PEAK HOLD waveforms, and overwrites the retained value if it is not... -
Page 24: Frequency
9.Operation Procedure If the method of capturing data is PEAK HOLD or MAX HOLD, the measurement results are not applied until the specified time in seconds has elapsed. After the specified time in seconds has elapsed, the operation becomes the same as when the checkbox is unchecked. Frequency The measurable frequency range depends on the spectrum analyzer and sound pressure sensor. -
Page 25: Microphone Sensitivity
9.Operation Procedure Microphone Sensitivity Enter the microphone’s own sensitivity value into the Microphone Sensitivity field. Enter the exact value of [Sensitivity: －xx.x dB] shown in the data sheet (graph sheet) included with the sound pressure sensor. GAIN Enter the GAIN value set for the microphone power supply into the GAIN field. Since the spectrum analyzer is highly sensitive, generally there is no problem when 0 dB is set. -

Page 27: Deleting Measurement Data
9.Operation Procedure The EPS-02Sv2 software sends a sweep start command to the spectrum analyzer immediately after the sensor is recognized. After completion of sweeping, the software recognizes the sensor position again, and only when the sensor is found at the same point (position) where it was placed at the start of the analyzer sweeping, the spectrum data is stored. -
