7.3 General Operating Notes
Keys . Do not be afraid to experiment with the keys. The AM-48 will
not accept an “illegal” or meaningless keystroke. If an out-of-
tolerance value is entered in a user-programmable variable field, the
display will default to an acceptable value.
Displays .
1. The units of measurement appear at the top of the display, above
the value. Time and count units are not shown, but are given in
the table associated with the corresponding display.
2. Display decimal points will flash when batteries are low.
3. Displays of “OVER” or “UNDR” indicate the signal being
monitored is too high or low to be read.
4. Depending on the mode, there may be multiple displays through
which one can scroll. All displays accessible form each mode
are shown in the figures.
5. To quickly go to the initial display from another display in a
scroll, momentarily exit and then re-enter the same mode by
moving the cursor. See the example in ¶5.7.
Check List . Go through the following check list to cover important
points while performing any operation:
1. Look at the cursor positions on the menus. These indicate what
SEND and MEASURE mode is selected and what noise-weighting
filter is selected.
