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.

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.

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
