Precautions for handling of components
Be sure to observe the following precautions to avoid injury and loss of life of personnel, and
damage to the equipment used.
●
Probe
Warning
Do not point the tip of the needle themo probe at a person. It is very sharp and may
cause injury.
Caution
• Do not touch the stylus (metal part) of a probe that has just been used to measure a
high temperature as it may cause a burn.
• Make sure that the potential differences between probes do not exceed 1 V.
• Do not use a worn or damaged probe, which may be incapable of correct tempera-
ture measurements.
• Before removing a probe from the TM20, pull the probe away from the object mea-
sured.
• When using a probe for liquids, such as a needle probe, insert it into the liquid to be
measured by approximately half the dimension of the probe’s stylus (metal part).
Inserting it too deeply may cause a burn due to heat transfer to the probe grip as
well as cause damage to the probe itself.
• The probe grip and the cable connected from the TM20 must be maintained at a
temperature between –20
°
C and 50
°
C. Unlike the stylus of a probe, these parts have
a low resistance to heat.
• When sending data in real-time, use an ungrounded probe.
