IM 01C50E01-01EN
NOTE
When storing the instrument with a battery pack,
it is recommended to put the instrument in Deep
Sleep mode to conserve the batteries. For details
on how to switch to Deep Sleep mode, refer to
subsection 7.3.14 “Switching to the Deep Sleep
Mode”.
2.4 Choosing the Installation
Location
Although the temperature transmitter is designed
to operate in a vigorous environment, to
maintain stability and accuracy, the following is
recommended.
 Wireless Communication
NOTE
The installation location of this transmitter must
meet the following conditions:
- Adjust the direction of the antenna to be
in the upright position regardless of the
orientation of this transmitter. See section 4
for adjusting the antenna.
- Install the transmitter at least 1.5 m above
the ground or floor.

1.5m or more
- Ensure that there are no obstacles such as
walls or pipes within a 30-cm radius of each
antenna.
- Confirm that each field wireless equipment
compliant with ISA100.11a can see the
antenna of other devices which locate within
its own communication range. In the star
topology network, the visibility to the antenna
of gateway is a mandatory clause.
 Ambient Temperature
It is preferable to not to expose the instrument to
extreme temperatures or temperature fluctuations.
If the instrument is exposed to radiation heat
a thermal protection system and appropriate
ventilation is recommended.
 Environmental Requirements
Do not allow the instrument to be installed in a
location that is exposed to corrosive atmospheric
conditions. When using the instrument in a
corrosive environment, ensure the location is well
ventilated.
The unit and its wiring should be protected from
exposure to rainwater.
 Impact and Vibration
It is recommended that the instrument be installed
in a location that is subject to a minimum amount of
impact and vibration.
 Installation of Explosion-protected
Transmitters
An explosion-protected transmitters is certified for
installation in a hazardous area containing specific
gas types. See subsection 2.7 “Installation of an
Explosion-Protected Transmitters.
2.5 Use of a Transceiver
IMPORTANT
Although the transmitter has been designed to
resist high frequency electrical noise, if a radio
transceiver is used near the transmitter or its
external wiring, the transmitter may be affected
by high frequency noise pickup. To test this, start
out from a distance of several meters and slowly
approach the transmitter with the transceiver
while observing the measurement loop for noise
effects. Thereafter use the transceiver outside
the range where the noise effects were first
observed.
