DewPro MMY31
4.2 Description of the DewPro MMY31 Programming Matrix
In the DewPro mid-range 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. For users of other General Eastern equipment, this 'GEI matrix" format is
familiar. The following describes the features and usage of the various matrix location as
they apply to the MMY 31.
Fig. 19
The display of the DewPro MMY 31 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 analogue fashion (refer to
Figure 19). See the Appendix for an enlarged overview of the matrix.

Movement through the matrix is accomplished by using the "V" and "H" buttons to move
to another row or column. For example, beginning at VH 00 and successively pressing
"V", leads the user to VH 10, VH 20, VH 30, VH 40, VH 50, VH 60, VH 70, VH 80, VH 90
and back to VH 00. At any location where a value may be changed by the user, the
desired value is programmed using the "+" and "-" buttons.
