SysCheck2TM is a GRAS patented technology for verifying measurement chain integrity. SysCheck2TM allows remote, simultaneous health check on microphones, channel gain and cable integrity.
GRAS 246A0 with SysCheck2TM is a high-precision microphone ideal for testing hearing aids, earphones, headphones, and headsets in ear simulators/couplers and test fixtures/chambers.
SysCheck2TM helps reduce human errors and increase data reliability both in the lab and on the production line. It is particularly convenient when microphones are placed where physical verification is a risk - for example, if the microphones are hidden in complex mechanical structures, such as couplers or specialized test boxes on production lines.
SysCheck2TM functionality can be accessed with many data acquisition systems but offers seamless plug-and-play operation with Audio Precision’s APx data acquisition software.
