ARNINGS AND OPERATING INSTRUCTIONS ON THE TEMPERATURE SENSORS
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. If the connector is fitted with a seal rubber ring (o-ring), make sure it is inserted all the way.
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 con-
tainer 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 substance that could corrode or damage it.
7. Avoid 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 or-
der 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. Probes are not insulated from their 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 IP66, but should not be immersed in water. Close the free
connectors using caps. The probe connectors must be fitted with sealing gaskets.

Instrument storage conditions:
•
Temperature: -25…+65°C.
•
Humidity: less than 90% RH without condensation.
•
During storage avoid locations where:
humidity is high,
the instrument may be exposed to direct sunlight,
