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.

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.

(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

and integral flow orifice unit, 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.
