16. Security Level Selection
The display will read “SL x”, where “x” is a “0”, “1”, or “2”. The “0” enables full
programming capability from the front panel for non-commercial applications.
The “1” enables limited front panel programming for commercial applications.
The “2” disables all front panel programming for commercial applications.

CAUTION:

a. If Security Level “1”, or “2 “ is selected at this step, Security Level “0”

CANNOT be selected at a later time from the front panel. Be sure of your selection

before you continue

b. If Security Level “1” is selected, program steps 3, 4, 5, 6, 7, 14 and 15 cannot

be changed from the front panel.

c. If Security Level “2” is selected, NO parameters can be changed from the front

panel

d. Security Level must be set to “1” or “2 “for commercial applications. If the

Security Level is set for “0”, the instrument is NOT considered “LEGAL FOR
TRADE”, therefore the Security Level should be set for “1 “ or “2” for any

commercial application.

17. Inhibit Switch Selection
The display will read “inhS x”, where x will be a “1” or a “0”. If “1” is selected then one
or more front panel switches may be inhibited from operating. If “0” is selected then
all switches are operational. All keys except the ENTER key may be inhibited. If “1” is
selected, the display will show which switches are inhibited upon re-entering
programming mode. If no switches are inhibited the display will be blank.

a. If the displayed list is acceptable, press the ENTER key.
b. If a new key inhibit list is wanted

1) Press the keys that are to be inhibited
2) When the list is complete, press the ENTER key

If there are more switches inhibited than the display can show at one time, the display
can be shifted over one switch at a time by pressing the FUNC key. Pressing the
ENTER key will retain the current list. If any other key is pressed the current list will be
cleared and a new one started. The new list will end when the ENTER key is pressed.

Some examples of this feature are:

a. The instrument is monitoring the weight of a hopper and the user is

afraid someone will accidentally ZERO the indicator and lose the weight
readings. By inhibiting the ZERO switch this can be prevented.

b. The supervisor feels the instrument is too complicated and the operator

could accidentally change the desired setup. Inhibit all the switches
except ZERO and that is the only key the operator can use.

c. Instrument is hooked to a remote computer and user doesn’t want

anyone to interfere with the computer control. Inhibit all the switches once
the indicator is setup.
