WARNINGS
AND
OPERATING
INSTRUCTIONS
1.
Do not expose the probes to gases or liquids that could corrode the probe sensor or the probe
itself. Clean the probe carefully after each measurement.
2.
Do not bend the probe connectors, forcing 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 probes in presence of corrosive gases or liquids; the sensor container is made of
AISI 303 stainless steel, while the contact probe container is of AISI 303 stainless steel plus
silver. Avoid contact between the probe surface and any sticky surface or substance that could
corrode or damage it. Should the sensor break or become faulty, it may be replaced. In this case,
the probe must be recalibrated.
7.
Above 400°C and below –40°C, avoid violent blows or thermal shocks to PT100 temperature
probes; this could cause irreparable damage.
8.
To obtain reliable temperature measurements, rapid temperature variations must be avoided.
9.
Temperature probes for surface measurements (contact probes) must be held in vertical position
with respect to the surface. Apply oil or heat-conductive paste between the surface and the
probe in order to improve contact and reduce reading time. Do not use water or solvent for this
purpose.
10.
Temperature measurements on non-metal surfaces usually require a great deal of time; this is
due to low heat conductivity of non-metal materials.
11.
Probes are not insulated from their external casing; be very careful not to come in 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, microwaves or large
magnetic fields; results could be not very reliable.
13.
Clean the probes carefully after use.
14.
The instrument is water resistant, but is not watertight and therefore, should not be immersed in
water. Should the instrument fall into the water, take it out immediately and check for water
infiltrations into it. Gently handle the instrument in such a way as to prevent any water
infiltration from the connectors side. Unconnected connectors should be closed using the
connector protections.
