INTRODUCTION
General and Safety Information
 Risk of Electrical Shock: Disconnect all power sources before making cable connections to
the floor scale platform or indicator.
 For use in dry environments only.
 Do not operate in hazardous areas.
 Read and understand all operating instructions before using this product. Keep this manual for
future reference.
 Record the weight shortly after placing a load on the platform. After extended periods, the load cell’s
output signal may result in a less accurate reading.
 Avoid extended exposure to extreme heat or cold. Optimum operation is at normal room
temperature. See operating temperature range in the specifications table. Allow the scale to
acclimate to room temperature before using.
 Allow sufficient warm up time. Turn the scale on and allow up to 2 minutes for internal components to
stabilize before weighing.
 Electronic scales are precision instruments. Do not operate near cell phones, radios, computers or
other electronic devices that emit radio frequencies that may cause unstable readings.
 This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with this manual, may cause harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful interference, in which case the user will
be required to correct the interference at their own expense.
 Avoid using in heavy vibration or heavy airflow conditions. This also applies when the floor scale is
integrated into conveying systems.

(1) The scale must have been calibrated before this adjustment
(2) The range of adjustment is “(current displayed weight) x (0.9-1.1)”. This means the
range is about ±10%
(3) The “CONFIG-REGULA =NONE” and “CONFIG-FUNC-WT.ADJ=YES” must be set.
1. To enter this mode, in normal weighing model, place a load (for example, the correct weight is
1230.0lb) onto scale, then indicator will display the load’s weight, shown as “1234.5lb”. Press
TARE/PRESET and ZERO/ON/OFF at same time until first digit flashes, which means indicator has
entered into “weight fine-tune” mode.
2. Use
key to input correct weight (1230.0). After confirmed by TARE/PRESET, the
Version 04.12

active correct weight will be displayed and the digits will no longer be flashing. Then, the
displayed weight will be adjusted by this ratio (1230.0/1234.5) and this ratio will be active until the
next modification.
3. To remove effect of this ratio, follow one of the two options below:
a. Perform standard calibration, refer to the section on “CALIBRATION”.
b. Remove weight from the scale, press the ZERO/ON/OFF to display 0 ,then place a load onto
the scale. A number will be displayed, for example it displayed 1230.0 lb but the original
number is 1234.5; press the TARE/PRESET and ZERO/ON/OFF at same time until first digit
flashes, which means indicator has entered into “weight fine-tune” mode. Press the SETUP
key for the displayed weight to be restored to 1234.5, and then press TARE/PRESET to
confirm and exit to normal weighing mode.
HOLD Function(closed on GW)
NOTE: In trade application, HOLD function should be prohibited!
1. HOLD function can be used to freeze the display number. In this mode, scale can catch a dynamic
number, hold a stable number, or average an unstable number, then HOLD (freeze) this number
temporary for the user to watch or record. This function can be used in normal weighing mode,
counting mode and percent weighing mode. After entering HOLD mode, the speed of A/D
converter can be increased to 80Hz (if USER-HOLD-AD.H.SPD is set to YES) from the original
10Hz for some dynamic weighing applications. With the hold function, it is possible to weigh
restless weighing samples such as live animals or moving objects. The indicator provides a
special mode setting to accommodate sample’s movements.
2. For the HOLD function to be active, the CONFIG-FUNC-HOLD menu item must be set to YES;
menu items of USER-HOLD-HLD.MOD /-AVG.TIM /-HLD.TIM /-STB.TIM, USER-OTHER-NLD.RNG
need be set to reasonable values.
To increase the speed for sampling of weight, set USER-HOLD-AD.H.SPD menu item to YES.
To enter HOLD working mode, press the SETUP key when scale is in normal weighing mode,
counting mode or percent weighing mode.
3. There are several HOLD modes use to freeze display data:
a. Positive Peak Number HOLD mode
b. Negative Peak Number HOLD mode
c. Toggle HOLD mode
d. Average HOLD mode
e. Auto HOLD mode
The following information contains details for these HOLD modes:
a. Positive Peak HOLD:
When USER-HOLD-HLD.MOD is set to PS.PEAK, the hold mode is positive peak hold
mode. When the scale first enters this working mode, it will display the largest positive
number that is from the time of zero-point set. After entering this working mode, the
scale will always catch and refresh with the largest positive number. To exit HOLD mode,
press the SETUP key.
Version 04.12
. 27.
GW Series
User/Service Manual
b. Negative Peak HOLD:
When USER-HOLD-HLD.MOD is set to NG.PEAK, the hold mode is negative peak hold
mode. When the scale first enters this working mode, it will display the largest negative
number that is from the time of zero-point set. After entering this working mode, the
scale will always catch and refresh with the largest negative number. To exit HOLD mode,
press the SETUP key.
c. Toggle HOLD:
When USER-HOLD-HLD.MOD is set to TOGGLE, the hold mode is toggle hold mode ---a
manual Hold function. After entering this working mode, the scale will freeze and display
number if the scale is stable. Only the weight that is over USER-OTHER-NLD.RNG (zero
'dead' band ) can be held. To exit HOLD mode, press the SETUP key. If the length of
time that the scale is unstable for more than USER-HOLD-STB.TIM, STB.ER will be shown,
press the TARE/PRESET key to start averaging again, or press the SETUP key to exit.
d. Average HOLD:
When USER-HOLD-HLD.MOD is set to AVERAG, the hold mode is average hold mode.
After entering this working mode, the scale will freeze and display number if the scale is
stable. If the scale is not stable, but the variation is less than USER-HOLD-HLD.RNG, the
scale will average data in USER-HOLD-AVG.TIM, then freeze and display the number. Only
the weight that is over USER-OTHER-NLD.RNG can be frozen. Scale will exit HOLD mode
according to the setting of USER-HOLD-HLD.TIM. If the time of scale variation is over
USER-OTHER-NLD.RNG or is more than USER-HOLD-STB.TIM, STB.ER will be shown,
press TARE/PRESET, UNIT/DATA, ACC/TOTAL or PRINT/FUNC to start averaging again,
or press SETUP key to exit.
e. Auto HOLD:(Default setting)
When USER-HOLD-HLD.MOD is set to AUTO, the hold mode is autohold mode: different
subjects can be weighed one after another without pressing any buttons. After entering
this working mode, the scale will freeze and display number if the scale is stable. If the
scale is not stable, but the variation is less than USER-HOLD-HLD.RNG, the scale will
average data in USER-HOLD-AVG.TIM, then freeze and display the number. Only the
weight that is over USER-OTHER-NLD.RNG can be frozen. If the held weight is removed,
and a new load is placed on the scale, the scale will automatically hold the new number
of the load. Scale will exit HOLD mode according to the setting of USER-HOLD-HLD.TIM.
If the time of scale variation is over USER-OTHER-NLD.RNG or is more than
USER-HOLD-STB.TIM, STB.ER will be shown, press TARE/PRESET to start averaging
again, or press SETUP key to exit.
4. In Positive or Negative Peak HOLD mode, the PEAK and HOLD annunciator will be lit, and for
other HOLD modes, the HOLD annunciator will be lit. When HOLD annunciator is flashing, the
displayed number is live. When HOLD annunciator becomes steady, the displayed number is
frozen.

5. Calibration
Note:
① Before calibrating the scale, please prepare a standard weight (more than 10% of FS
weight) for calibration.
② In the following steps, pressing ZERO/ON/OFF will show “EXIT?”, and pressing
ZERO/ON/OFF again or pressing TARE/PRESET will exit the calibration
1. Go to setup mode, select “CAL”, then press TARE/PRESET to confirm to enter calibration mode.
2. After entering this mode, the number of times that the indicator has been calibrated will be shown
first, this number will be increased after every calibration and the calibration data will be saved.
This counter can not be modified or erased by any other way, it counts from 0000 to 9999, when it
reaches 9999, it will start over at 0000. After the counter number is displayed, it will show
“CAL.OFF” or “CAL.ON” according to the status of the sealed calibration switch is OFF or ON.
If the switch is OFF, the following steps can be completed, but the result will not be saved. Press
TARE/PRESET key to continue.
3. When “ZERO” is shown, use
keys to select ZERO to perform zero point calibration (refer
to step4), LINE to perform linearity calibration (refer to step5), GEO to do Geographical
calibration (refer to step 6) or INPUT to Input/view calibration parameters value (refer to step
7).
 ZERO Calibration
4. When ZERO is selected, remove all weight from the scale and press the TARE/PRESET key to
confirm, the ZERO will flash when it is in the catching zero point state. After receiving reasonable
data, it will automatically continue to step8.
 Linearity Calibration
5. When LINE is selected, press TARE/PRESET key to enter linearity calibration.
a. 0% weight will be displayed after CAL.P0 is shown, remove all weight from the scale and then
press TARE/PRESET to confirm to calibrate the zero point; the zero weight will flash in
catching zero point state. After calculating the reasonable zero-point data, the zero weight will
become steady
b. When the first default standard weight is displayed after CAL.P1 is shown, it will be calibrated
on standard weight for the first point. Place the corresponding weight (more than 10%FS
weight) onto the scale. The default standard weight is 100%FS. Usekeys to input the value of
the loaded weight. Before entering this value, you can press and hold the UNIT/DATA key to
change the unit of measure to kg or lb. Press the TARE/PRESET key to confirm, then the
indicator will flash the input standard weight. When this weight number becomes steady, it
means the stable and reasonable data corresponding to the standard weight has been

received. After this, the indicator will automatically continue to the next step. If this point can
not be calibrated correctly (E.g. the weight load on the scale is too small, the input data is
incorrect…), it will display “CAL.Er” and return to step a for re-calibration.
When End.y is shown and y is flashing, enter a command to exit calibration or go on to the
next calibration. Use
keys to select yes or no, use TARE/PRESET to confirm. If yes is
selected, you will be directed go to step8 to end calibration; if no is selected, continue to the
next step.
When 100%FS weight is displayed after CAL.P2 is shown, it will be calibrated on standard
weight for the second point. Place corresponding weight (more than 10%FS weight, and larger
than the weight used on CAL.P1) onto scale. The next operation steps are the same as
explained in step b.
When End.y is shown and y is flashing, Use
key to select yes or no, use TARE/PRESET
to confirm. Refer to step c for more details.
When the third standard weight displayed after CAL.P3 is shown, it will be calibrated on
standard weight for the third point. Place corresponding weight (more than 10%FS weight,
and larger than the weight used on CAL.P2) onto the scale. The next operation steps are the
same as explained in step b.
When the stable and reasonable data corresponding to the standard weight has been received,
the indicator will automatically go to Step8. Otherwise, it will display “CAL.Er” and return to
the previous steps.
 GEO Calibration
6. When GEO is selected, press TARE/PRESET key to confirm to enter Geographical Adjustment.
When “CODE” is shown, use
keys to select geographical position code or input the local
gravity value directly.

View ADC output Code
In this mode, you can examine the stability of the weighing system, which is the increment value of
ADC output code corresponding to the loaded weight.
Note:
① The increment of ADC code for FS weight must be larger or equal to 10 times of the
selected display division; otherwise, the calibration cannot be properly completed. E.g. The
display division is 0.1kg. Load 100kg standard weight on the platform, the increment of
ADC code should be at least more than 10x100kg/0.1kg= 10x1000=10000. In this case,
the scale can be calibrated. Otherwise, a smaller division needs to be chosen.
② The variation of the ADC code should be small; otherwise, the calibration cannot be
properly completed.
