2.11 Temperature Measurement
Never apply voltage to the test leads. Doing so may
damage the instrument and result in personal injury.
To avoid electrical accidents, remove power from
the circuit before measuring.
• The sensor used in the temperature probe is a thin,
precision platinum film. Be aware that excessive volt-
age pulses or static discharges can destroy the film.
• Avoid subjecting the temperature probe tip to physical
shock, and avoid sharp bends in the leads. These may
damage the probe or break a wire.
• When measuring high temperatures, do not let the
handle of the temperature probe or the compensation
lead wire exceed the temperature range.
• Clean the surface of the object to be measured, and
then touch the temperature probe firmly to the sur-
face.
• If a temperature greater than the ambient tempera-
ture is to be measured, move the temperature probe
along the surface of the object being measured until
the maximum reading is obtained.
• If a temperature below the ambient temperature is to
be measured, move the temperature probe along the
surface of the object being measured until the mini-
mum reading is obtained.
• The sub display shows the environmental tempera-
ture according to the internal temperature sensor.
