SysCheck2™ is a new GRAS-patented technology by which the two new microphones GRAS Type 246AE (free-field) and Type 246AO (pressure field) are equipped with a high-precision built-in microprocessor able to generate a reference signal that enables remote verification of the entire measurement chain. It is a tool that allows test and production engineers to remotely check the health of microphones, channel gain and cable integrity.
It is easy to set up with standard cables making it adaptable for any testing setup and is highly recommended for applications such as production line, distributed measurement setups, and anywhere where regular and rapid human-free function measurement verification + environment sensing (temperature, pressure and humidity) is required.
The verifications are easily made on each SysCheck2™-enabled microphone connected to a CCP/IEPE/ICP/CCLD power module with transducer electronic data sheet (TEDS) support and measurement software. SysCheck2™ functionality also provides on-demand environmental data: temperature, barometric pressure and humidity.
They are intended as simple and cost-effective interfaces between TEDS-enabled measurement microphones and analysers which will automatically extract TEDS data for seamless integration. It can also be used with other analysers that do not offer automated interrogation, using a utility program to access the TEDS data using a PC. This program can be downloaded from the GRAS website.
Validation of CFD (Computer Fluid Dynamics) modelling is an important part of designing vehicles. However, airflow and turbulence cannot be fully simulated and predicted realistically. For these reasons, high-quality measurements are a must.
