USER MANUAL

• Risk of electric shock: disconnect all power sources before making cable connections to the
floor scale platform or indicator.
• For use in dry environments only.
• The floor scale platform is very heavy. Use appropriate lift equipment.
• Scale platform must be installed on a foundation capable of safely supporting the weight of
the floor scale plus the weight of the maximum load.
• Do not operate in hazardous areas.
• Read & 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. Power on the scale by pressing the ZERO/ON/OFF key.
2. If the display stabilizes but doesn’t show zero, press the ZERO/ON/OFF key to set new zero point.
3. Place the objects on the scale platform and read the weight on the indicator.
Note: Objects should be placed at the center of the platform. Corner or side loading heavy
objects may risk overloading an individual load cell and damage the scale.
4. To change the weight unit of measure, press the UNIT/DATA key.
5. To send data to another device via the serial port, press the PRINT/FUNC key.
6. Power off the scale by pressing the ZERO/ON/OFF key for 4 seconds.
1. Zero the scale as described above.
2. Place an empty container on the platform, press the TARE/PRESET key. The display will return to
zero, eliminating the weight of the container. NET will be lit on the display.
3. Place the material or object to be weighed in the container. The net weight will be displayed.
4. To exit tare mode, remove all weight from the scale. The display will show a negative weight. Press
the TARE/RESET key to return the display to zero.
1. Zero the scale as described above.
2. Press and hold the TARE/PRESET key until is displayed, then the tare weight will be
displayed. The first digit and NET will flash in the display.
3. Input the tare weight using the ↑↓→keys. After inputting the tare weight, press the TARE/PRESET
key to confirm. NET will be lit in the display.
Note:Tare weight must be greater than zero and no more than the scale’s max capacity.
4. Place the material or object to be weighed onto the scale platform. The net weight will be displayed.
5. To exit tare mode, remove all weight from the scale. The display will show a negative weight. Press
the TARE/RESET key to return the display to zero.
Note: The indicator can only save 1 tare weight. Entering a new tare weight will automatically replace
the old one.
Note: Pre-set tare weight will be lost after the scale is powered off.
OPERATIONS & SETTINGS
NORMAL WEIGHING MODE
YES NO NO
TARE FUNCTION
This scale allows for both a manually entered pre-set tare weight, as well as a “weighed” tare weight.
WEIGHED TARE
PRE-DETERMINED TARE
1. If the display does not show 0, and there is no object on the platform, press the ZERO/ON/OFF key
to zero the reading.
• Zero range: ±2% * full capacity.
• The zero function is unavailable when the displayed reading is out of the zero range and the indicator
will show the error message or meaning the scale is over or under the zero range.
ZERO FUNCTION

The check weighing or data compare function allows the user to input a pre-set range,
and the display will indicate whether the weighed value is within that range, and indicate
if it is too high or too low.
The accumulation function allows storage of weighed values and the summation of those values.
This function can accumulate weights, piece counts, and percentages in normal weighing mode,
counting mode, and percent weighing mode respectively.

CHECK WEIGHING (DATA COMPARE)
ACCUMULATION MODE
1. Press and hold the UNIT/DATA key for 4 seconds to input the comparative data range.
2. or will be displayed first. Use the UNIT/DATA keys to select the
comparison unit of measure. Press the TARE/PRESET key to confirm.
3. After is shown quickly, the last Hi limit value will be displayed
(the default value is ).
HI on the display will be lit. Use the ↑↓→ keys to input the upper limit of the range and press
the TARE/PRESET key to confirm and move to the next step.
4. will be displayed quickly, the last Lo limit value will be displayed
(the default value is ). LO on the display will be lit. Use the ↑↓→ keys to input the
lower limit of the range and press the TARE/PRESET key to confirm. Press ZERO/ON/OFF key
to exit and go back to the normal weighing mode.
NOTE: If the upper limit is 0, or if it is less than the lower limit, check weighing mode will
automatically be exited.
5. After an acceptable range has been set, check weighing may begin. If the weighed value is within
the specified range, OK will be displayed on the indicator and an audible beep will sound. If the
value is outside the specified range, HI or LO will be displayed with no audible beep.
6. To turn check weighing off, follow the above instructions and change the upper limit to zero.
1. With a load on the scale, press the ACC/TOTAL key to add the displayed value to the
accumulated total. The indicator will first display the times of accumulation (e.g. if this is the 5th
accumulated value, it will display ), and then display the accumulated sum total thus
far, then it will display the load weight.
NOTE: Only loads exceeding the minimum weight (default of 10d, where d = the scale’s
readability, see specifications) can be accumulated. This setting (USER-OTHER-NLD.RNG) can
be modified from its default within USER SETUP mode, but changes will impact other functions
such as HOLD.
2. Remove the load and place another load to continue accumulating, press and release ACC/
TOTAL to add the new value.
NOTE: To avoid duplicating a value for a same load, the accumulation function requires the
original load to be removed before a new value can be accumulated.
3. To view the total accumulated data at any time, press and hold the ACC/TOTAL key for 4
seconds. It will alternatively display the accumulation times and the accumulated sum total thus
far (weight or quantity), until the ACC/TOTAL key is pressed again. Accumulated times and total
values can be displayed or sent to another device via the serial port by pressing and releasing the
PRINT/FUNC key.
4. To clear and reset the accumulated data, press and release the ZERO/ON/OFF key while total
accumulated data and the accumulated sum total are alternatively displayed.
