a mild detergent.
Calibration
TSI recommends an annual calibration for the instrument. For a nominal fee, we will calibrate the unit
and return it to you with a certificate of calibration and NIST traceability. This “annual checkup” assures
you of consistently accurate readings. To calibrate the instrument, please ship the complete package that
includes the meter, the base, the manifold and any fabrics used. Everything should be packed carefully
within the carrying case and then inside a shipping box. The original shipping box is preferred.
Tables 6 and 7 list the symptoms, possible causes, and recommended solutions for common problems
encountered with the instrument. If your symptom is not listed, or if none of the solutions solves your
problem, please contact the factory.
