KEYPAD MATRIX
For maximum flexibility in operation, the HI-3603 has a keyboard
matrix for the upper three keypads on the membrane switch
panel. The function of each of the three keys can be changed
depending on the location of the CURSOR block in the LCD
display. The cursor block is a dark rectangle located at the
bottom edge of the LCD display. On turn on, the cursor is located
above the leftmost of the three columns of functions on the
control panel. In this mode the functions of the three topmost
keys are as follows:
A. SCALE
B. MAX
C. E/H
MODE SELECT - Pressing the MODE keypad moves the cursor
to the right; each push of the pad moves the cursor one position.
From the third, or rightmost, position, the cursor moves around to
the first position. This allows a total of nine (9) different functions
to be assigned to the three keypads.
The MODE SELECT keypad is also used to change the display
response filters as well as the magnetic field units of measure.
When the meter is turned on, a self-test procedure is
automatically performed. As part of this procedure, all segments
of the display are lit for about two seconds. To review or change
the filter and unit settings, press and hold the MODE SELECT
keypad while all the segments are lit. In this mode two settings
can be changed. Pressing the E/H keypad will step through the
filter settings. Pressing the MAX keypad will step through the H-
field units of measure. Refer to the descriptions of the E/H and
MAX keypads for further details. When the settings are adjusted
to the desired values, again press the MODE SELECT keypad to
leave the setup mode and begin normal measurement operation.
The operational description of the various functions is as follows:
