2. Handling Cautions
This chapter provides important information on how
to handle the transmitter. Read this carefully before
using the transmitter.
The transmitters are thoroughly tested at the
factory before shipment. When taking delivery of an
instrument, visually check them to make sure that
no damage occurred during shipment.
Also check that all transmitter mounting hardware
shown in figure 2.1 is included. If the transmitter
is ordered without the mounting bracket and the
process connector, the transmitter mounting
hardware will not be included. After checking the
transmitter, carefully repack it in its box and keep it
there until you are ready to install it.

2.3 Storage
The following precautions must be observed when
storing the instrument, especially for a long period.
(a) Select a storage area which meets the following
conditions:
• It is not exposed to rain or subject to water
seepage/leaks.
• Vibration and shock are kept to a minimum.
• It has an ambient temperature and relative
humidity within the following ranges.
Ambient temperature:
–40* to 85°C without integral indicator
–30* to 80°C with integral indicator
* –15°C when /HE is specified.
Relative humidity:
0% to 100% R.H.
Preferred temperature and humidity:
approx. 25°C and 65% R.H.
(b) When storing the transmitter, repack it carefully
in the packaging that it was originally shipped
with.
(c) If the transmitter has been used, thoroughly
clean the chambers inside the cover flanges, so
that there is no process fluid remaining inside.
Before placing it in storage, also make sure that
the pressure-detector is securely connected to
the transmitter section.

Location
The transmitter is designed to withstand severe
environmental conditions. However, to ensure
that it will provide years of stable and accurate
performance, take the following precautions when
selecting the installation location.
