1 General Information and Warnings
1.1 About this Manual
This manual is divided into chapters by the chapter number and the large text at the top
of a page. Subsections are labeled as shown by the 1 and 1.1 headings shown above.
-The names of the chapter and the next subsection level appear at the top of alternating
pages of the manual to remind you of where you are in the manual. The manual name
and page numbers appear at the bottom of the pages.
1.1.1 Text Conventions
The keys used to interface with the 67XXU are located on the front panel of the
indicator. The keystrokes are shown in BOLD incased between brackets. (e.g. [ZERO])
Displayed messages appear in seven segment display type and reflect the case of the
displayed message. (e.g. confg)
1.1.2 Special Messages
Examples of special messages you will see in this manual are defined below. The
signal words have specific meanings to alert you to additional information or the relative
level of hazard.
CAUTION!
This is a Caution symbol.
Cautions give information about procedures that, if not observed, could result
in damage to equipment or corruption to and loss of data.
ELECTRICAL WARNING!
THIS IS AN ELECTRICAL WARNING SYMBOL.
ELECTRICAL WARNINGS MEAN THAT FAILURE TO FOLLOW
SPECIFIC PRACTICES OR PROCEDURES MAY RESULT IN
ELECTROCUTION, ARC BURNS, EXPLOSIONS OR OTHER HAZARDS
THAT MAY CAUSE INJURY OR DEATH.
NOTE: This is a Note symbol. Notes give additional and important information, hints
and tips that help you to use your product.
67XXU USB/Serial Scale Service Manual 5
Page 6
1.2 Warnings
l Avoid lengthy exposure to extreme heat or cold. Your scale works best when
operated at normal room temperature. Always allow the scale to acclimate to
a normal room temperature before use.
l Allow sufficient warm up time. Turn the scale on and wait for a few minutes if
possible. This will give the internal components a chance to stabilize before
weighing.
l These electronic scales are precision instruments. Do not operate near an
in-use cell phone, radio, computer or other electronic device. These devices
emit RF and can cause unstable scale readings. If your scale ever performs
poorly, try moving the scale to a different room or location.
l Avoid using in heavy vibration and airflow conditions.
l Read the weight reading in short time after loading. The output signature of
load cell and electronic circuit may be little influenced after weighing for a
long time.
1.3 Routine Maintenance
IMPORTANT: This equipment must be routinely checked for proper operation
and calibration.
Application and usage will determine the frequency of calibration required for
safe operation.
Always turn off the machine and isolate from the power supply before starting any
routine maintenance to avoid the possibility of electric shock.
1.4 Sharp Objects
Do not use sharp objects such as screwdrivers or long fingernails to operate the keys.
1.5 Cleaning the Indicator
Table 1.1 Cleaning DOs and DON’Ts
DO DO NOT
Wipe down the outside of standard products
with a clean cloth, moistened with water and
a small amount of mild detergent

6.5 Weight Fine-tune
With this function, the user can adjust displayed weight a little without the need of
standard weight. But please note:
l The scale must have been calibrated previously
l The range of adjustment is "(current displayed weight) x (0.9-1.1)". This
means the range is about ±10%
l The CONFG-REGUL=NONE and CONFG-FUNC-WT.ADJ=YES must be
set.
1. To enter this mode, turn on indicator. After the indicator displays a 0 weight,
place weight onto scale. The indicator will display the weight.
2. Press down [TARE] and [ZERO] at same time until the first digit flashes, this
means indicator has entered into "weight fine-tune" mode.
3. Use the arrow keys to input correct weight.
4. Press the [TARE] key to confirm. The active correct weight will be displayed.
The displayed weight will be adjusted by this ratio (130.0/1234.5). The ratio
will be active until the next modification.
5. Recalibrate the scale or use the Weight Fine Tune method to readjust the
ration.
6.6 Display ADC Output Code
In this mode, you can examine the stability of weighing system and increment the ADC
output code corresponding to the loaded weight. Please note the following:
l The increment of ADC code for full scale weight must be larger or equal to
10 times of selected display division. Otherwise, the calibration cannot be
properly completed.
m 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.
l The variation of the ADC code should be small. Otherwise, the calibration
cannot be properly completed.

8 Legal for Trade
Push Button
The 67XXU Model must be configured to meet regulations mandated by local weights
and measures authorities.
8.1 Physical Seal
The configuration/calibration push button is used to protect the scale from being
configured or calibrated under legal for trade conditions. When set to legal for trade and
sealed with a lead seal, the scale can only be configured and calibrated by authorized
personnel.
The push button is located under the center screw on the underside of the scale.
Remove the center screw. Press the button with a non-metallic object or a #0 phillips
screwdriver.
CAUTION!
Do not use a flat blade screwdriver or other small metallic object as this could
damage the scale!

8.2 Audit Trail Parameters
Two separate incrementing, non-resetable audit trail parameters are used to indicate
changes to various parameters or calibration.
8.2.1 View Configuration Counter
1. Press and hold the [HOLD] + [ON/OFF] key for 3 seconds. CONFG is
displayed.
2. Press the [TARE] key to view the configuration counter.
2a. The display will briefly show the number of times the configuration has been
changed and will save up to 9999. This counter can't be modified or erased. It
counts from 0000 to 9999. When 9999 is reached, the counter starts over at
0000. The display will then show whether the configuration switch is on
(cf.on) or (cf.off) off.
To Exit:
1. Press the [ON/OFF] key twice. Exit? is displayed.
2. Press the [TARE] key to return to the working mode.
8.2.2 View Calibration Counter
1. Press and hold the [HOLD] + [ON/OFF] key for 3 seconds. CONFG is
displayed.
2. Use the [PRINT] key to select the CAL menu.
3. Press the [TARE] key to enter the calibration mode.
3a. After entering this mode, the number of calibrations will be shown first. This
number will be increment one digit after every time a calibration has been
performed and saved. This counter can't be modified or erased. It counts from
0000 to 9999, when 9999 is reached, the counter starts over at 0000.
4. After the counter number was displayed, it will show "Ca.OFF" or "CAL-ON"
which depends on whether the sealed calibration switch is OFF or ON. If the
switch is OFF, the following steps can be done, but the result will not be
saved.
To Exit:
1. Press the [ON/OFF] key twice. Exit? is displayed.
2. Press the [TARE] key to return to the working mode.
