STARTUP and OPERATION
Rosemount Analytical µCEM Continuous Analyzer Transmitter 4-11
4.3 µ CEM Settings
The µCEM Settings dialog is only available to users with µCEM Settings permission. If a
user is not currently logged in, the login dialog will be displayed. If the current user
doesn’t have µCEM Settings permission, µCEM will not allow Settings screen to appear.
When the µCEM Settings are invoked from the Advanced menu or the µCEM Settings
button, the µCEM Settings tabbed dialog is displayed. The Range page (tab) is
displayed initially.
4.3.1 µCEM Settings-Range
The Range Settings page is used to specify the range for the analog outputs. Setting
Range 2 to a value of 0 (zero) enables single range functionality and disables the
dual range function. For Dual Range applications do not set range 2 equal too or
higher than Range 1 or the system will not calibrate properly. Note that Range 1 can be
changed by the user but must be changed in the webrowser tools. See the Webrowser
user settings section.
The dual range setting will enable the analyzer software and diagnostics to perform two
separate performance curves for each range thus enhancing the measuring capabilities
of the analyzer. A dual range setting is desired for applications burning dual fuels or that
may display high dynamic reading between the low and high of the day. The analog
outputs will also support the dual range mode. When the emission is below the Range 2
value, the analog output will switch to Range 2 mode and the Range 2 value becomes
the full-scale value of the analog output. The range indication digital output will change
to the Range 2 state. When the emission is above the Range 2 value, the output
switches to Range 1 mode and the Range 1 value becomes the full-scale value of the
output. The range indication digital output will change to the Range 1 state.
