WARNINGS
AND
OPERATING
INSTRUCTIONS
1.
Do not expose the probes to gases or liquids that could corrode the material of the
sensor or the probe itself. Clean the probe carefully after each measurement.
2.
Do not bend the probe connectors or force them upward or downward.
3.
Do not bend or force the contacts when inserting the probe connector into the
instrument.
4.
Do not bend, deform or drop the probes, as this could cause irreparable damage.
5.
Always select the most suitable probe for your application.
6.
Do not use the temperature probes in presence of corrosive gases or liquids. The
sensor container is made of AISI 316 stainless steel, while the contact probe
container is made from AISI 316 stainless steel plus silver. Avoid contact between
the probe surface and any sticky surface or product that could corrode or damage
it.
7.
Above 400°C and below –40°C, avoid violent blows or thermal shocks to Platinum
temperature probes as this could cause irreparable damage.
8.
To obtain reliable measurements, temperature variations that are too rapid must
be avoided.
9.
Temperature probes for surface measurements (contact probes) must be held
perpendicular against the surface. Apply oil or heat-conductive paste between the
surface and the probe in order to improve contact and reduce reading time.
Whatever you do, do not use water or solvent for this purpose. A contact
measurement is always very hard to perform. It has high levels of uncertainty and
depends on the ability of the operator.
10.Temperature measurements on non-metal surfaces usually require a great deal of
time due to the low heat conductivity of non-metal materials.
11.The sensor is not insulated from its external casing; be very careful not to come
into contact with live parts (above 48V). This could be extremely
dangerous for the instrument as well as for the operator, who could be
electrocuted.
12.Avoid taking measurements in presence of high frequency sources, microwave
ovens or large magnetic fields; results may not be very reliable.
13.Clean the probe carefully after use.
14.The instrument is water resistant and IP67, but should not be immersed in water.
The probe connectors must be fitted with sealing gaskets. Should the instrument
fall into the water, check for any water infiltration. Gently handle the instrument in
such a way as to prevent any water infiltration from the connectors' side.
