2. HANDLING CAUTIONS
2. HANDLING CAUTIONS
This chapter describes important cautions regarding
how to handle the transmitter. Read carefully before
using the transmitter.
The EJA-A Series pressure transmitters are thoroughly
tested at the factory before shipment. When the
transmitter is delivered, visually check them to make
sure that no damage occurred during ship-ment.
Also check that all transmitter mounting hardware
shown in Figure 2.1 is included. If the transmitter was
ordered without the mounting bracket or without the
process connector, the transmitter mounting hardware
is not included. After checking the transmitter, repack
it in the way it was delivered until installation.

2.2 Unpacking
When moving the transmitter to the installation site,
keep it in its original packaging. Then, unpack the
transmitter there to avoid damage on the way.
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 water.
• It suffers minimum vibration and shock.
•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:
5% to 100% R.H. (at 40°C)
Preferred temperature and humidity:
approx. 25°C and 65% R.H.
(b) When storing the transmitter, repack it as nearly as
possible to the way it was packed when delivered
from the factory.
(c) If storing a transmitter that has been used, thor-
oughly clean the chambers inside the cover flanges,
so that no measured fluid remains in it. Also make
sure before storing that the pressure-detector and
transmitter section are securely mounted.
