HANDLING CAUTIONS

This chapter provides important information on how to
handle the transmitter. Read this carefully before using
the transmitter.
EJX Series 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.

2.2 Unpacking

Keep the transmitter in its original packaging to
prevent it from being damaged during shipment. Do
not unpack the transmitter until it reaches the installa-
tion site.

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
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.
