QUsb488jv.dll not found is displayed on the PC when trying to use the application software for Model 3197 Power Quality Analyzer.
The 3197 application software requires JAVA’s 32-bit JRE. Please install and use the 32-bit JRE (Java Runtime Environment) regardless of whether the Windows OS is in 64-bit or 32-bit.
Note: If both the 32-bit JRE and the 64-bit JRE are installed in your PC, the PC may only recognize the 64-bit version. In that case, please:
1. Uninstall 64-bit Java first
2. Re-install with 32-bit Java
You can download the most recent JRE here:
