purpose weighing scales with parts counting, percent weighing and
check-weighing unctions.
•The GBK/GFK has LEDs to indicate when a weight is below the low limit,
between the limits or above the high limit next to the display. These
can work in conjunction with an audible alarm or check weighing as
well as LCD showing LO, OK and HI.
•The GBK/GFK is supplied with a RS-232 bi-directional inter ace and real
time clock (RTC).
•The GBK/GFK has a sealed keypad with colour coded membrane
switches and a large easy to read liquid crystal type display (LCD)
supplied with a backlight.
•Includes automatic zero tracking, semi-automatic tare and
accumulation acility that allows the weight to be stored and recalled as

3.1. UNPACKING
The GBK/GFK scales have already been adjusted to work with a plat orm and have
been con igured or this application. The plat orm and indicator have been
calibrated as a pair and must be used together .
3.2. LOCATING
•The scales should not be placed in a location that will
reduce the accuracy.
•Avoid extremes o temperature. Do not place in direct
sunlight or near air conditioning vents.
•Avoid unsuitable tables. The table or loor must be rigid
and not vibrate.
•Avoid unstable power sources. Do not use near large
users o electricity such as welding equipment or large
motors.
•Do not place near vibrating machinery.
•Avoid high humidity that might cause condensation.
Avoid direct contact with water. Do not spray or
immerse the scales in water.
•Avoid air movement such as rom ans or opening doors.
Do not place near open windows or air-conditioning
vents.
• Keep the scales clean. Do not stack material on the
scales when they are not in use.

10 | P a g e © Adam Equipment Company 2010
3.3 SETT NG UP THE SCALES
•The pillar is attached to the base using a bracket that must be attached
to the base rame irst using the 4 bolts supplied. The pillar is secured
to the bracket using 2 sets o screws. The cable rom the base to the
indicator module is run through the tube and taken out through the
plastic support at the top. Excess cable can be stored within the tube.
•The GBK/GFK Series comes with a stainless steel plat orm packed
separately. Place the plat orm in the base.
•Level the scale by adjusting the our eet. I the scale rocks re-adjust the
eet.
•Attach the indicator module to the pillar by sliding it over the bracket
with the langes engaged in the groves on the base. Attach the cable
rom the base to the connector on the rear o the indicator.
•Attach the power to the indicator. Press the [On/Off] key. The so tware
revision number will be displayed ollowed by a sel -test showing all
digits be ore the zero is displayed along with the unit o weight that was
selected last.
•I the scale is an approved version, GBK/GFK..M, and the Calibration
Counter has been enabled (see section 6) the current values will be
displayed. These values should match the values marked on the scale
at the time o veri ication, i it has been veri ied.

14 | P a g e © Adam Equipment Company 2010
Next to the LCD are a number o LED’s that show when the weight is below, within
or over the limits during check weighing.
Weight LED LCD
below the low limit Amber LO
Within the limits Green OK
Above the high limit Red HI
NOTE: The LED’s can be set by the user to o , bar, spot or segment mode. See “F3
LED” in section 13.1
The LED can be set to display as a bar, increasing rom Low to OK to High, a single
spot increasing rom Low, OK to High, or as a single bar that changes colour as the
weight progresses rom Low to OK to High.
6. CAL BRAT ON COUNTER FOR APPROVED SCALES
The approved (GBK/GFK-M Model) scales have the ability to control access to the
calibration or metrology parameters using a passcode to limit access. The
requirements or doing this stipulate the code should be apparent and recorded in a
suitable location on the scale.
In this way i the record o the Calibration or Parameter counters do not agree with
recorded settings the responsible person inspecting the scale can take appropriate
action.

15 | P a g e © Adam Equipment Company 2010
The Counters are incremented any time the calibration section or the Factory
parameters section have been modi ied.
At power on, the display will show the current so tware revision number ollowed
by the message o the Calibration Count “[AL[nt” then a number i.e. “123”. The
number rom the counter memory. Then the Parameter Counter message o
“PAr[nt” and probably a di erent number, i.e. “234”. The counters cannot be
reset to 0, they will increment until the display can no longer hold the values. (1 to
999999). It is expected we will never have more than 1 million calibrations in the
li e o the machine.
Each display is held or 1-2 seconds.
The scale will then continue to do the display test and go to normal weighing.
I during the time the counting displays are shown, the user presses the [Tare] key,
the user will be given a message to enter the passcode necessary to calibrate the
scale, “P - - - - “ Enter the code “P0000” to Enter calibration or “P1000” to enter
the parameters, ollowed by pressing the [Tare] key.
The Calibration access will allow user calibration (See section 15.1) and the
parameter code will allow access to the ollowing parameters. (see section 15.2).
“F4 Int” Initial Zero Range
“F5 rEZ” Re-Zero range
“F6 SCS” Successive Tare Enable
“F7 Cnt” Display ADC counts
“F8 Zem” Zero Mode
“F9 Lvd” Low voltage detection

7. BATTERY
•The scales can be operated rom the rechargeable battery, i desired.
The GBK/GFK scales have up to 70 hours battery li e be ore needing to
be recharged i the backlight is disabled and the battery is ully charged.
•When the battery needs charging a symbol on the display will turn on.
The battery should be charged when the symbol is on. The scale will still
operate or a period o time a ter which it will automatically switch o
to protect the battery.
•To charge the battery, simply plug into the mains power supply. The
scale does not need to be turned on.
•The battery should be charged or 12 hours or ull capacity.
•To the right o the display is a LED to indicate the status o battery
charging. When the scale is plugged into the mains power the internal
battery will be charged. I the LED is green the battery is being charged.
I it is red it is nearly discharged and yellow indicates the battery is
increasing the charge level. Continue to charge overnight or a
complete re-charge.
8. BACKL GHT
The backlight or the LCD can be set by the user to always o , always on or
automatic (on only when the scale is in use or a key is pressed). See setting o the
parameter “S2 bL” in section 13.3.
9. AUTO POWER OFF
The auto power o can be set by the user to disable the eature or to a pre-set time
interval. See setting o the parameter “S3 AoF “ in section 13.3.

17 | P a g e © Adam Equipment Company 2010
10. OPERAT ON
10.1. ZEROING
•You can press the [Zero] key at any time to set the zero point rom
which all other weighing and counting is measured. This will usually be
necessary when the plat orm is empty. When the zero point is obtained
the display will show the zero indicator.
•The scale has an automatic re-zeroing unction to account or minor
dri ting or accumulation o material on the plat orm. However you may
need to press [Zero] to re-zero the scale i small amount o weight is
still shown when the plat orm is empty.
10.2. TARING
10.2.1 MANUAL TARE
•Zero the scale by pressing [Zero]. The zero indicator will be on. Place a
container on the plat orm and its weight will be displayed.
•Press [Tare] when the reading is stable. The weight that was displayed
is stored as the tare value and it is subtracted rom the display, leaving
zero on the display. The stable and Net indicator will be on.
•As a product is added only the weight o the product will be shown. The
scale could be tared a second time i another type o product was to be

18 | P a g e © Adam Equipment Company 2010
added to the irst one. Again only the weight that is added a ter taring
will be displayed.
NOTE:
When the container is removed a negative value will be shown. I the scale was
tared just be ore removing the container, this value is the gross weight o the
container plus all products which were removed. The zero indicator will also be on
as the plat orm is back to the same condition it was when [Zero] was pressed last.
Press [Tare] or [Zero] to remove the tare value and display zero. The Net indicator
will disappear.
10.2.2 PRESET TARE (NOT AVA LABLE ON APPROVED SCALES)
When the scale is at zero with no weight on the plat orm it is possible to enter a
preset tare.
•Zero the scale by pressing [Zero]. The zero indicator will be on.
•Enter a value using the numeric keys.
•Press [Tare] to tare the scale. The value that was entered is stored as
the tare value and it is subtracted rom the display, leaving a negative
number on the display.
