<2. Handling Cautions> 2-1

IM 01C25C01-01E

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gure2.1isincluded.Ifthetransmitter

is ordered without 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.

Figure 2.2 Name Plate

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

installation 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

*–15°Cwhen/HEisspecied.

Relative humidity:

0% 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 carefully

in the packaging that it was originally shipped

with.

cleanthechambersinsidethecoveranges

and the diaphragm surface of high pressure-

detector section, so that there is no process

uidremaininginsideoronit.Beforeplacingit

in storage, also make sure that the pressure-

detector is securely connected to the transmitter

section.
