4-2 The Optional Display/User Interface (Option G)
Description of the
DewPro MMY30
Programming Matrix
In the DewPro trace moisture transmitter with display option, a
matrix-style input is used for programming the unit of measure,
measuring range, error status of output, and output adjustment. Each
option is assigned coordinates on the 10 by 10 matrix, specified with
V (vertical), H (horizontal) and a number for each. You select the
desired option by entering the matrix position.The following sections
describe the features and usage of the various matrix locations as they
apply to the MMY30.
Figure 4-2: The MMY30 Optional Display
The display of the DewPro MMY30 continuously shows the current
matrix location using the vertical (V) and horizontal (H) coordinates
to designate the row and column, respectively. The bar graph
represents the output current in an analog fashion (refer to Figure 4-2
above). See Appendix A for an enlarged overview of the matrix with
all possible options, shown in Table 4-1 below.
