Programming the Matrix
In the MMR31 with the display option, a matrix-style input is used for programming the units of measure, measuring
range, error status of output, and output adjustment.
Note:
For users of other Panametrics equipment, this matrix format may be familiar. However, this section
describes the features and usage of the various matrix locations only as they apply to the MMR31.
The MMR31 display (see
below) 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.

The
V
and
H
buttons are used to move to another row or column in the matrix (see
). For example,
to select location
VH 45
from a starting location of VH 00, press
V
four times and then press
H
five times to arrive at
VH 45 (i.e., row 4 and column 5).
At any matrix location where the matrix value may be changed by the user, the digit to be changed is flashing, and
the desired value is programmed using the
+
and
–
buttons. For example, at matrix location
VH 01
, the desired
moisture units are selected by choosing from the matrix values listed in
below.
