Pico NVH Standard Diagnostic Kit Including PicoScope 4425A Oscilloscope EP043

Noise, vibration, and abnormal noise

For current technicians, PicoDiagnostics developed by Pico Technology ® NVH The kit provides low-cost and efficient solutions for many NVH issues. It provides real-time diagnosis in the following ways: a bar chart, a frequency chart, a 3D frequency chart, and an RPM or vehicle speed window. It can start recording before the road test and replay the recording for analysis after returning to ensure that the driver's attention is focused on the road. Saving records with it is very simple, just like our other car software, you can easily save files to your computer's hard drive.

PicoDiagnostics ® NVH The kit is compatible with PicoScope 4000 series automotive oscilloscopes and is suitable for various configurations of vehicles (inline, V-type; manual, automatic) to meet your needs (excluding J2534 scanning tool or VCI). Because software upgrades are free for life with no additional expenses, ensuring that you can benefit from this investment. If you already have the PicoScope 4000 series car oscilloscope, you already have half of this device.

Classic applications:

Customer complaints about noise/vibration are the most subjective, which poses a challenge for current technicians before conducting diagnosis and correction. By connecting the NVH kit to the vehicle, technicians can conduct a road test with the customer to capture all vibration and noise amplitudes.

After collecting these useful data, you can analyze and compare them with previous data, or compare them with data from the same vehicle model. Usually, the "problem" vibrations perceived by customers are actually the characteristics of the vehicle itself. Now, you can obtain objective data and compare it with the data collected on the same vehicle model, eliminate customers' doubts and tell them everything is normal. Additionally, by comparing data, it may highlight issues with the vehicles; With the support of measurement data, technicians can confidently carry out repair work.

Here are some classic applications of NVH kit that help you save time and money:

• Vibration inside the passenger cabin at a certain speed
• Engine vibration throughout the entire speed range
• Clutch tremor/vibration
• Transmission and bearing noise (whining)
• Auxiliary drive noise
• Brake tremor
• Steering wheel vibration
• ………………

NVH issues

The root cause of all NVH issues is vibration. On the one hand, these are unwanted or unexpected vibrations, and on the other hand, they are always present (such as engine combustion), but in any case, they should not be transmitted to the driver or passenger.

Sound is actually a vibration transmitted through air (or other media), which is "heard" by humans when it reaches their ears. Although the ideal auditory range is 20 Hz to 20 kHz, most people can hear up to 100 Hz to 15 kHz. Vibration is usually "felt" and has a frequency below 200 Hz. The vibration can be felt and heard within the frequency range of 20 Hz to 200 Hz.

To effectively handle these frequency ranges, the PicoDiagnostics NVH kit includes a microphone (for sound) and an accelerometer (for vibration).

Traditionally, NVH issues have been difficult to solve. Complaints about NVH are subjective, as different people have varying levels of acceptance and perception towards NVH. Technicians need the right tools and processes to effectively solve this problem, objectively, repetitively, and easily diagnose complaints about NVH. The PicoDiagnostic NVH suite is such a tool that can generate reports for customers showing that their complaints have been fully addressed.

Setup Wizard and NVH Help

Pico's NVH system has a series of guides that guide you through the necessary device connections and vehicle information input, and then generate easy to understand test results.

This testing system detects vibrations (and sounds), including frequency changing vibrations (such as wheels, engines, driveshafts, etc.) and frequency fixed vibrations (such as electronic cooling fans). The test results are displayed in an easy to understand report format and can be presented in a view that suits you.

The complete help file explains the reasons and solutions, and the software provides features that allow you to easily diagnose problems using logical methods, ultimately revealing the root cause of the problem. The same function also allows you to display test results to customers to verify the effectiveness of your repairs or fixes.
