SCALE - The SCALE keypad changes the fixed ranges or scales
of the instrument. When turned on, the HI-3603 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.
To return to the AUTO RANGE mode, press and hold the
SCALE keypad until the AUTO indication is shown in the upper
left area of the LCD.
MAX - While using the instrument for field measurements, the
processor is continually saving the highest indicated reading. To
recall and display the highest reading, press the MAX keypad.
This maximum reading is indicated as long as the MAX keypad
is activated. The maximum reading is indicated by the MAX
indication near the right edge of the LCD. On releasing the MAX
keypad, the reading is held for about two seconds and then the
memory is cleared and a new maximum reading accumulated.
When the instrument is shifted between the electric and the
magnetic field mode, the MAX reading memory is cleared.
The MAX keypad is also used to adjust the H-field units of
measure. This is done just after the meter is turned on. During
the self-test routine, the display will show all segments lit. When
all the segments are lit, press and hold the MODE SELECT
keypad to enter the display setup mode. Hold the MODE
SELECT keypad until the display reads "F-#" and the current H-
field unit of measure. Press the MAX keypad to scroll through the
available units. Once the desired units are selected, press the
MODE SELECT keypad to save the current setup, leave the
setup mode, and begin normal measurement operation.
