Installation
Installation Location
Install the GX70SM indoors in an environment that
meets the following conditions:
• Ambient temperature range between -20 to 70°C.
• Ambient humidity between 0 to 90%RH.
No condensation should be present.
Note
Condensation may form when moving the GX70SM from
a low temperature or humidity environment to a high
temperature or humidity environment, or when there is a
sudden change in temperature. Temperature or humidity
changes may also result in thermocouple measurement
, humidity measurement errors. In these kinds of
circumstances, wait for at least an hour before using the
GX70SM, to acclimate it to the surrounding environment.
• Minimal mechanical vibrations
Install the GX70SM in a location that has minimal
mechanical vibrations. Installing the GX70SM in a location
that is subject to large levels of mechanical vibration will
not only put added stress on its components, it may also
impede ordinary measurement.
Do Not Install the Instrument in the Following Places
• Outdoors
• In direct sunlight or near heat sources
Install the GX/GP in a place that is near room temperature
(23°C) and that is not subject to large temperature fluctuations.
Placing the GX70SM in direct sunlight or near heat sources
can cause adverse effects on the internal circuitry.
• Where an excessive amount of soot, steam, moisture,
dust, or corrosive gases are present Soot, steam,
moisture, dust, and corrosive gases will adversely affect
the GX70SM. Avoid installing the GX70SM in such
locations.
• Near strong magnetic field sources
Do not bring instruments that produce electromagnetic
fields close to the GX70SM. Operating the GX70SM near
strong magnetic fields can cause measurement errors.
Installation Procedure

the GX70SM terminals.
Make sure that pulling force is not directly applied to
the terminals of this product.
● Topreventre,usesignalcableswithatemperature
rating of 70°C or more.
● Donotapplyvoltagesthatexceedthefollowingval-
uestotheinputterminals.Doingsomaydamagethe

● ThisinstrumentconformstoovervoltagecategoryI,
Pollutiondegree2,MeasurementcategoryO.
Precautions to Be Taken While Wiring
Take the following precautions when wiring the input signal
cables.
● We recommend the following wire.
Cross-sectional
area
0.08 mm2to 2.08 mm2(AWG28 to 14)
Stripped wire
length
5 to 6 mm
● Take measures to prevent noise from entering the
measurement circuit.
• Move the measurement circuit away from the power
cable (power circuit) and ground circuit.
• Ideally, the object being measured should not generate
noise. However, if this is unavoidable, isolate the
measurement circuit from the object.
Also, ground the object being measured.
• Shielded wires should be used to minimize the noise
caused by electrostatic induction. Connect the shield to the
ground terminal of the GX70SM as necessary (make sure
you are not grounding at two points).
• To minimize noise caused by electromagnetic induction,
twist the measurement circuit wires at short, equal
intervals.
• Make sure to earth ground the functional ground terminal
through minimum resistance.
● When using internal reference junction compensation on
the thermocouple input, take measures to stabilize the
temperature at the input terminal.
• Do not use thick wires which may cause large heat
dissipation (we recommend a cross sectional area of 0.5
mm2or less).
• Make sure that the ambient temperature remains
reasonably stable. Large temperature fluctuations can
occur if a nearby fan turns on or off.
● Connecting the input wires in parallel with other devices
can cause signal degradation, affecting all connected
devices. If you need to make a parallel connection, then
• Turn the burnout detection function off.
• Ground the instruments to the same point.
• Do not turn ON or OFF another instrument during
operation. This can have adverse effects on the other
instruments.
• RTDs cannot be wired in parallel.
