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:
SCALE - The SCALE keypad changes the fixed ranges or scales
of the instrument. When turned on, the HI-3604 is in the AUTO
RANGE mode. The unit determines the correct range within the
current mode (E or H field) according to the detected field level.
As the field being measured increases or decreases, the range
is automatically selected for best resolution and accuracy.
In some situations, it may be helpful to fix the scale of the
instrument. Pressing the SCALE keypad once fixes the
instrument on the current scale setting. Each successive
operation of the keypad moves the scale to the next least
sensitive range. When the least sensitive scale has been
selected, the next operation of the keypad will shift to the most
sensitive range again.
