To address an erratic zero reading on your TSI Incorporated Measuring Instruments, start by checking the connections for any leaks. Inspect the inlet port and sample tube for dirt. If internal filters are not installed properly, replace the zero filter and clean the inlet port and tubing. Ensure the filters and o-rings are seated correctly in the internal filter wells, replacing the internal filters if needed.
