STATUS ONE Display Mode
The STATUS ONE screen displays the Rate A PL, Total A, and the analog output value in mA. This screen
is useful for setup or troubleshooting. A typical display is:
ANALOG OUT Display Mode
The ANALOG OUT display mode displays the analog output command value in milliamps.
This is the commanded value, not the actual value, and under certain conditions some difference could
occur between the displayed value and the actual mA output value.
The two‐digit number shown after ANALOG OUT indicates what the output represents. In this case, “00”
indicates that the output represents RATE A GT. See the Analog Point parameter for more information
regarding output assignment.
ANALOG OUT Programming
Program the signal assignment, offset, and scaling values for the mA output from the ANALOG OUT
display screen. The output can represent rate or total, and you can program the flow rate or total value
represented by the maximum output. Use the MODE/DN button (or magnetic switch) to select the
ANALOG OUT display.
To program, press and hold the ENT button (or maintain the ENT magnetic switch). The display first
shows a P in the lower left‐hand corner and then displays the first program variable for this mode. Three
parameters are accessed in order:
 MA OFFSET
 ANALOG POINT
 ENTER VALUE AT MAX MAs
MA OFFSET
This variable is used to set to lowest value for the mA output span and as a fine offset adjustment in the
field, if necessary. The low range of the output span is programmable between 4.00 and 10.00 mA. The
RT‐15 will not accept a value less than 4 mA. The RT‐15 utilizes the output device AD421 manufactured
