WARNING
The local push button on the integral indicator
must not be used in a hazardous area. When
it is necessary to use the push button, operate

theexplosion-proof/ameprooftypetransmitter,
please refer to section 2.9 for each product.
IMPORTANT
• Donotturno󰀨thepowertothetransmitter
immediately after performing parameter
setting.Poweringo󰀨within30secondsof
performing this procedure will return the
parameter to its previous setting.
• The parameters of Ext SW for HART
or J55:EXT ZERO ADJ for BRAIN, to
enable or inhibit zero point adjustment
by means of the zero-adjustment screw
on the transmitter must be“Enabled” to
performthisconguration.Pleasereferto
either IM 01C25T01-06EN for the HART
communication type, or IM 01C25T03-01E
for the BRAIN communication type for the
