Maintenance
Probe Tip
Periodically inspect the probe tip to ensure that it is clean. Dust and oil
deposits on the velocity sensor decrease the accuracy of the V
ELOCI
C
ALC
.
Caution: The V
ELOCI
C
ALC
must be switched off for cleaning. Do not
use high-pressure air, strong solvents, or brushes to clean the
sensor tip; damage to the sensors could result.
To remove dust, blow it off with a gentle stream of air or rinse it off with a
gentle stream of water. To remove a combination of dust and oil, rinse the
probe tip in isopropyl alcohol and then blow it off with a gentle stream of
air.
Be careful not to get the humidity sensor wet! (The humidity sensor on
Models 8360 and 8388 is located at the base of the probe window, just
inside the antenna tube.) Also, for the 8383, be careful not to allow water to
enter the articulating probe joint.
Caution: Never use heat to dry the probe. Permanent damage to the
sensor could result.
Recalibration
To maintain a high degree of accuracy in your measurements, TSI
recommends that you return your instrument for annual recalibration. For a
nominal fee, we will recalibrate the unit and return it to you with a certificate
of calibration and US National Institute of Standards Technology (NIST)
traceability. This 'annual checkup' assures you of consistently accurate
readings; it is especially important in applications where strict calibration
records must be maintained.
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 submerge the
V
ELOCI
C
ALC
.
Storage
When storing the V
ELOCI
C
ALC
for more than a month, it is recommended to
remove the batteries. This prevents damage due to battery leakage.
