3. Handling Precautions
CAUTION
• Each probe has its own maximum and minimum operating temperatures,
so ensure that its temperature does not fall outside the specied range.
• As the probe is susceptible to corrosion, do not use the instrument for the measurement of
gas or liquid, and refrain from measuring semi-solid particles and semi-viscous substances.
After measurement, wipe the probe with a dry cloth.
• Do not apply a strong force to the upper and lower parts of the probe as doing so may
result in the bending of the probe connector.
• When using the instrument be careful not to bend, drop, or strike the measurement probe.
• When measuring surface temperature using a surface-type probe, position the probe
perpendicular to the surface of the object. Also note that the application of oil to the probe
for the means of providing better contact can improve measurement accuracy.
• When measuring non-metallic surface temperature, make sure the measurement time is
long enough to compensate for poor thermal conductivity.
• To ensure stable measurement, the instrument should not be subjected to a sudden
temperature change.
• This instrument, with the exception of the connector section, is water-resistant but not
waterproof. Therefore the instrument should not be immersed in water.
If it is mistakenly immersed in water, remove it immediately and check to ensure that no
water has penetrated inside the case. Although this instrument is designed so that
any water penetrating into the connector does not permeate into the circuit inside the case,
try to prevent any water entering the connector. If water does enter the connector,
the burnout display may be unavailable.
Attention
• Chaque sonde possède ses propres températures de fonctionnement maximales et
minimales. Il faut donc s'assurer que sa température ne tombe pas sous la plage spéciée.
• La sonde étant sensible à la corrosion, ne pas utiliser l'instrument pour la mesure de
gaz ou de liquide et éviter de mesurer des particules semi-solides et des substances
semi-visqueuses. Après la mesure, essuyer la sonde avec un chion sec.
• Ne pas exercer une force puissance sur les parties supérieures et inférieures de la sonde,
car cela risquerait de faire plier le connecteur de sonde.
• Lors de l'utilisation de l'instrument, faire en sorte de ne pas plier, faire tomber ou cogner
la sonde de mesure.
• Lors de la mesure de la température de surface à l'aide d'une sonde de type sonde
de surface, placer cette dernière perpendiculairement à la surface de l'objet.
Noter que l'application d'huile sur la sonde an d'assurer un meilleur contact peut
améliorer la précision de la mesure.
• Lors de la mesure de la température sur une surface non-métallique, s'assurer que
la durée de la mesure est susante pour compenser la mauvaise conductivité thermique.
• Pour assurer une mesure stable, l'instrument ne doit pas subir de changement de
température brutal.
• Cet instrument, à l'exception de la partie connecteur, est résistant à l'eau, mais pas
étanche à l'eau. C'est pourquoi l'instrument ne doit pas être immergé dans l'eau.
S'il se retrouve par erreur immergé dans l'eau, le retirer immédiatement et s'assurer que
l'eau n'a pas pénétré à l'intérieur du boîtier. Même si l'instrument est conçu pour que toute
quantité d'eau pénétrant dans le connecteur n'entre pas dans le circuit du boîtier,
il faut essayer d'éviter que de l'eau entre dans le connecteur.
Si de l'eau entre dans le connecteur, l'écran endommagé risque d'être indisponible.
