2.6 Compact to Remote / Remote to Compact conversion instructions
Conversion of the mounting of the signal converter from compact to remote, or vice-versa, is possible
under certain circumstances, using a kit of parts.
A change from compact to remote or vice versa in the field is possible in safe areas, for hazardous areas
only in the workshop.
Contact your local KROHNE Company and provide the serial number of the meter for further details.
