Why does my TSI Instruments Measuring Instruments show an erratic zero reading?
A
Antonio MorganAug 25, 2025
An erratic zero reading can be caused by several factors:
* A leak: Check all connections and tighten sample inlet screws carefully. If using an impactor, clean and re-oil the impactor disc, ensuring the O-ring is in place and the disc is seated correctly.
* A dirty inlet or sample tube: Clean the inlet and either clean or replace the tubing.
* Extreme temperature swings: Zero the instrument at ambient temperature before starting and protect it from temperature fluctuations.
* Contamination of the internal optics chamber: The unit may need to be returned to the factory for cleaning and servicing.
