MODE SELECT
The keypad uses a matrix for the top three rows of keys. The function of each
key depends on the location of the cursor in the LCD. When the readout is turned
on, the cursor is located in the first of the four function columns. To access a
function in this mode, press the corresponding arrow key. For example, to toggle
between electric and magnetic field measurements, press the lowest arrow key.
Press MODE SELECT to move the cursor to the right, advancing to the next
column. Each time MODE SELECT is pressed, the cursor moves another
position to the right, and then returns to the first position. This matrix allows a
total of 12 functions to be assigned to the top three rows of keys. Following is a
description of each of the functions.
RANGE
This changes the fixed
ranges or scales. When
turned on, the HI-3804
is in AUTO RANGE
mode, and 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 HI-3804. Press RANGE
once to select the current scale setting. Each time you press RANGE the scale
moves to the next least sensitive range. When the least sensitive scale is
reached, it starts again at the most sensitive range.
