NAVIGATING THE MENU

A "Menu Flow Chart" (Fig. 5) shows all of the possible commands which can
appear on the display, and their relationship. We've tried to simplify the
menu system by minimizing the number of screens and buttons. With a little
practice, it should become quite easy to find your way around.
Each menu is numbered on the flow chart, and the connecting lines and
arrows create a "highway" map to guide you through the system.
When power is applied, the metal detector will sequence through a number
of self-test screens, ending with Menu 7. This screen is the "RUN" menu,
and it will appear on the display whenever the detector is operational.
The "RUN" display shows which product number the metal detector is ready
to inspect. It also shows the number of detections that have occurred
since the counter was last reset.
The top line indicates that the unit is in "RUN" mode, followed by a
status indicator. If all is normal, the status will show "UNIT OK." During
detection, the status will show "REJECT ACTIVE." If for some reason the
output relays have been deactivated, the status indicator will show "NO
REJECT." The top line will alternately flash with the time and date.
The bottom line of all menu screens will give the operator some indication
of how to proceed if a change needs to be made.
The * key is used to scroll through the items on the screen. Pressing the
# key activates that item (wherever the cursor is), and moves you to the
next menu.
If you need to enter a number, use the number keys. Then press the # key
("enter") and the new value will be entered. Pressing * key ("escape")
will allow you to leave that screen without changing the value.
SET-UP PROCEDURES

SETTING THE DETECTOR TO COMPENSATE FOR PRODUCT EFFECT

One of the basic principles that should be understood before adjusting the
metal detector is product effect. Almost all products inspected are
conductive to some degree, and create a signal which is picked up by the
metal detector. This occurs without the presence of metal. This product
effect will cause the detector to false trip, and must be suppressed in
order to make reliable detection possible.
Product effect is caused mainly by moisture, but can also result from
product acidity, fat, mass, temperature, or salt (when combined with
moisture).
Products can be classified as wet or dry. Wet products, such as fresh
meats, cheese, and pickles create large product effect signals.
