1.
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.

UNPACKING & SETUP
1. Remove the scale from the box and place it on a firm, level surface. Avoid locations
with rapid temperature changes, excessive dust, moisture, air currents, vibrations,
electromagnetic fields, heat or direct sunlight.
2. Adjust the leveling feet until the bubble is centered in the circle of
the level indicator (located on the front panel).
NOTE: Ensure that the scale is level each time its location
is changed.
3. The internal rechargeable battery should be fully charged for up to 12 hours before
using the scale for the first time.
4. Connect the supplied AC adapter to the power input receptacle underneath the scale.
Plug the AC adapter into a properly grounded power outlet. The battery will begin
charging.
5. If the scale will be stored or transported in the future, save the packaging material to
ensure the best possible protection for the scale.

OPERATIONS & SETTINGS
POWER ON / POWER OFF
1. Place the scale on a flat, stable surface. Level the scale using the leveling bubble at the lower left
side of the display.
2. With the weighing platter empty, press the ON/OFF/ZERO key to power on the scale. The

scale will display a zero reading.
NOTE: The proper (power-on zero-point) range is: (calibration zero-point) ±20% FS
3. To power off the scale, press and hold ON/OFF/ZERO key.
ZEROING THE DISPLAY
1. You can press the ON/OFF/ZERO key at any time to set the zero point from which all other weighing
is measured. When the zero point is obtained, the display will show the indicator for zero.
2.
ZERO key range is (power-on zero-point) ±5% FS. ZERO function is only activated when the scale
is in steady weighing mode and this also clear the recorded tare weight, the ZERO indicator will be
lighted on, NET indicator will be off. ZERO function will be not activated when the current weight is

not in the range of (power-on zero-point) ±5% FS, and it will display “
back to previous weight reading.
NORMAL WEIGHING MODE
When scale is powered on and back to 0, place the weighing objects on the platform. The display will show
the weight and the units of weight currently in use.
TARING
1. Zero the scale by pressing the ON/OFF/ZERO key if necessary when reading is stable. The zero
indicator will be on.
2. Place a container on the platform, a value for its weight will be displayed.
3. Press the TARE/UNIT key to tare the scale. The weight that was displayed is stored as the tare value
and that value is subtracted from the display, leaving zero on the display. The "NET" indicator will
be on. As product is added only the weight of the product will be shown. The scale could be tared a
second time if another type of product was to be added to the first one. Again only the weight that is
added after taring will be displayed.
4. When the container is removed a negative value will be shown. If the scale was tared just before
removing the container this value is the gross weight of the container plus all product that was
removed. The zero indicator will also be on because the platform is back to the same condition it was
when the ON/OFF/ZERO key was last pressed. Note: TARE range for this scale is up to 100%FS.
SWITCHING UNIT OF MEASUREMENT
In normal weighing mode, press and hold TARE/UNIT key to switching the measuring units between lb, kg, g, oz, lb:oz.
