Maintenance
The Alnor AVM430/Airflow Instruments TA430 requires very little
maintenance to keep it performing well.
Recalibration
To maintain a high degree of accuracy in your measurements, we
recommend that you return your Alnor AVM430/Airflow Instruments
TA430 to TSI for annual recalibration. Please contact one of TSI’s
offices or your local distributor to make service arrangements and to
receive a Return Material Authorization (RMA) number. To fill out an
online RMA form, visit TSI’s website at http://service.tsi.com.
The Alnor AVM430/Airflow Instruments TA430 can also be
recalibrated in the field using the CALIBRATION menu. These field
adjustments are intended to make minor changes in calibration to
match a user's calibration standards. The field adjustment is NOT
intended as a complete calibration capability. For complete, multiple-
point calibration and certification, the instrument must be returned to
the factory.
Cases
If the instrument case or storage case needs cleaning, wipe it off with
a soft cloth and isopropyl alcohol or a mild detergent. Never immerse
the Alnor AVM430/Airflow Instruments TA430. If the enclosure of the
Alnor AVM430/Airflow Instruments TA430 or the AC adapter
becomes broken, it must be replaced immediately to prevent access
to hazardous voltage.
Storage
Remove the batteries when storing the unit for more than one month
to prevent damage due to battery leakage.
