Each axis is factory calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The IMU runs off a single 5 V supply and communicates through a standard RS422 interface. For advanced users, STIM320 may be put in Service Mode. In this mode all the configuration parameters can be intermediately or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte. STIM380H also has a Bias Trim Offset function, allowing the user zero out any bias offset of all six axes individually. The bias offsets can be stored in the flash memory to remain in effect after powering off the IMU.
The STIM evaluation tool offer easy measurement and configuration access for STIM gyro modules and IMUs. The tool supports data sampling at alternative rates, graphical data presentation and data log to file for up to two gyro modules/IMUs in parallel. RS422 interface for PCI or USB, necessary cabling and PC software is included in the evaluation tool.
