In order to obtain peak performance from the EXA
transmitter, you must set it up for each custom
application. Refer to APPENDIX A-1-2 for stand-
ard configurations and options.
Output range: mA output is set as default
to 0 - 20ppm.
For enhanced resolution in more
stable measuring processes, it may
be desirable to select for example
5-10 ppm range.
Hold The EXA DO202 transmitter has the
ability to “HOLD” the output during
maintenance periods. This
parameter should be set up to hold
the last measured value, or a fixed
value to suit the process.
Service This selection provides access to
the service menu.
