1 .2 .3 .1 The GS8920’s Normal Operating Mode.
The GS8920 is operating correctly and is ready for function key inputs when :-
1. There are NO error messages displayed.
2. The READY and FUNCTION lamps are ON to indicate that the
GS8920 is ready for one of the function keys to be operated.
In its normal operating mode, the WAIT lamp will flash briefly at approximately 2 second intervals as
the GS8920 obtains sets of data from the weight indicator. The GS8920 obtains this data to keep its
information up to date on the state of the weight indicator.
1 .2 .3 .2 Key Descriptions and Uses.
The following describes what happens following operation of each of the GS8920’s keys :-
ID/0 Key.
Displays the message
-Id x-
for ID number entry and is used as the numeral 0.
Following operation of the
ID
key, the message
-Id x-
is displayed and the numeral keys are active.
Any 6 digit ID number may now be keyed in. Operating the
key while entering an ID number
will cause the ID number in the display to be placed in the GS8920’s print buffer for inclusion at the
top of the next printed ticket. The message
-Id x-
will again appear in the display to show that the
GS8920 is ready for another ID number. The ‘x’ in the message shows the number of ID numbers that
have been placed into the GS8920’s print buffer.
Depending upon the way in which the GS8920 was set up at installation, a 12 character description
may also be printed with the ID number. Up to 6 description/ID number combinations may be printed
out of a total of up to nine ID numbers.
The GS8920 is returned to its normal operating mode by keying
ENTER
to save the ID number
presently displayed or by keying
CLEAR
while
-Id x-
is displayed. Keying
CLEAR
twice while a
numeral is displayed also returns the GS8920 to its normal operating mode.
A new ID number is not saved and does not therefore replace the permanently stored ID number unless
the
ENTER
key is pressed. ( The “x” above is a number in the range 0 to 9. )
AC+/1 Key.
The next weight received from the digital weight indicator is added to the active accumulator and a
ticket is printed. If the GS8920 has been set up for parts counting and item entry, then the quantity and
price per unit weight will need to be entered prior to the GS8920 printing a ticket. Used also as
numeral 1.
AC-/2 Key.
The next weight received from the digital weight indicator is subtracted from the active accumulator
and a ticket is printed. If the GS8920 has been set up for parts counting and item entry, then the
quantity and price per unit weight will need to be entered prior to the GS8920 printing a ticket. Used
also as numeral 2.
WEIGH IN/3 Key.
The next weight received from the digital weight indicator is saved to the first available empty tare
register and a “weigh in” ticket is provided. The tare register used becomes the active tare register.
Used also as numeral 3.
WEIGH OUT/4 Key.
tr —
is displayed and the tare register number used at the “weigh in” must now be entered. The
GS8920 will ONLY accept a tare register number which has been used to acquire a weight at the
“weigh in”. All other tare register numbers are ignored. Following entry of a proper tare register
number the next weight is obtained from the digital weight indicator. The GS8920 then compares the
weight in the tare register with the weight just obtained at the “weigh out” and uses the larger as the
Gross weight and the smaller as the Tare weight.
