4.2 Description of the DewPro MMY30 Programming Matrix
In the DewPro MMY30 trace moisture transmitter with display option, a matrix-style input is used for programming
the unit of measure, measuring range, error status of the output, and the output adjustment. Each option is assigned
coordinates on a 10 x 10 matrix, specified with a V (vertical row) address and an H (horizontal column) address, with a
number of 1-10 for each location. 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 DewPro MMY30.
Figure 15: 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 (see Figure 15 above). See Appendix A or Table 2 below for a list of the matrix functions.
