What to do if the TSI Instruments Measuring Instruments show 'Flow Error'?
- Jjames77Sep 7, 2025
If the TSI Instruments Measuring Instruments indicates a 'Flow Error', and you are sampling from a duct, attach both the input and exhaust ports into the duct. If the error persists, check for and remove any flow obstructions. Press any key to bypass the error. If the problem continues, factory service may be required. Also, replace the filter cassette.
