Analog Output
The analog output option translates the indicators’ display
reading to a proportional analog output signal. There are two
versions of the analog output option, either 0-10VDC or 4-
20ma. Both voltage and current outputs are scaleable within
their ranges and are similarly programmed. Note that the
analog output is active only in the display mode. As soon as
the
indicator is put in the program mode, indicated by a P in
the lower right hand corner of the display, the output goes to
its zero output value. The display reading can be scaled from
-999 to +9999, which enables the user to use only a portion of
the full scale if necessary.
