Remarks
Used to mount the PR300 according to the ANSI 4-inch round
form size or JIS110-square instrument size.
Used to mount the PR300 according to the DIN 96-square
instrument size.
Attached onto the top of the PR300 main unit.
Attached to the PR300 terminal section. (Must always be
attached to avoid a possible electric shock.)
Used in RS-485 communication if the
PR300
is a terminal device.
A quick reference manual for use in initial installation.
This CD contains all manuals related to the PR300.
