Operation Manual
1. Introduction
General and Safety Information
•For use in dry environments only
•This product uses 4xAA batteries. Dispose of according to local laws and regulations.
•Read and understand all operating instructions before using this product. Keep this manual
for future reference.
• Allow sucient warm up time. Turn the scale on and allow up to 10 minutes for internal
components to stabilise before weighing.
• Record the weight shortly after placing a load on the platter. Leaving loads in place for
extended periods may vary the load cell’s output signature and 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.
• When storing the scale for extended periods, the battery must be charged every 90 days
to avoid premature performance degradation. Over time, the operating time per charge will
degrade. If the operating time is no longer acceptable even after recharging, the battery
must be replaced.
• Electronic scales are precision instruments. Do not operate near cell phones, radios,
computers of other electronic devices that emit radio frequencies that may cause unstable
readings.

2. Unpacking and Setup
3. Overview of Controls and Functions
•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.
•Adjust the leveling feet until the bubble is centred 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.
•The internal rechargeable battery should be fully charged for up to 12 hours before using
the scale for the first time.
• 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.
• If the scale will be stored or transported in the future, save the packaging material to
ensure the best possible protection for the scale.

Operation Manual
4. Operations
4.1 Power on/Power o scale
•Place the scale on a flat, stable surface. Level the scale using the leveling bubble at the
lower left side of the display.
•With the weighing platter empty, press the ON/OFF/ZERO key to power on the scale. The
self-check will run, show the version number “V02”, display full capacity e.g. “F15.000kg”
at last, the scale will display a zero reading.
(Note: the proper (power on zero-point) range is: (calibration zero-point) ±20% FS).
• To power o the scale, press and hold ON/OFF/ZERO key.
4.2 Zeroing the Display
•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.
• 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 light will be on, NET indicator will be o. ZERO function will not be
activated when the current weight is not in the range of (power on zero-point) ±5% FS,
and it will display “0------” or “0_____”, then back to previous weight reading.
4.3 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.
4.4 Taring
•Zero the scale by pressing the ON/OFF/ZERO key if necessary when reading is stable. The
zero indicator will be on.
• Place a container on the platform, a value for its weight will be displayed.
• 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 the only weight that is added after taring will be displayed.
• 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.

4.5 Switching measuring unit
•In normal weighing mode, press and hold TARE/UNIT key to switching the measuring units
between lb, kg, g, oz, lb:oz
5. Calibration
6. AUTO-OFF Setting and BACKLIGHT Setting Function
1. Prepare standard weights and make the scale with no load.
2. When the scale is o, press and hold down TARE/UNIT button, and then press
ON/OFF/ZERO button at the same time until CAL-0 appears. Release the two buttons.
3. Be sure no weight is on the scale and press ON/OFF/ZERO button, “0” in CAL-0 will flash.
4. When CAL-F is displayed, press and hold TARE/UNIT button to choose the unit (kg of lb) of
standard weight in calibration; load full capacity weight on the platter. Then press
ON/OFF/ZERO button, F in CAL-F will flash.
5. When CAL-0 appears again, remove the weight from the platter and then press
ON/OFF/ZERO button. “0” in CAL-0 will flash.
6. When calibration has been completed properly, the scale will reset to normal working
mode. If CAL.Er is displayed, that means there is an error in calibration and needs to be
re-calibrated.
7. In Step 3 to Step 5, press and hold ON/OFF/ZERO to exit calibration mode.
When the scale is on, press and hold TARE/UNIT and ON/OFF/ZERO buttons until SETUP
is displayed, then A.oFF.XX is displayed (xx=0,1....9: means when the scale has no weight
changing and no key pressed for 1....9 minutes, the scale will auto- power o to save
battery power, when x=0, means no auto-power o function); Now press TARE/UNIT
button to choose the auto-o time and press ON/OFF/ZERO button to confirm and save the
setting.
The scale will display BLT.X (x=0, 1, 2.0: means backlight is always o, 1 means backlight
is always on, 2 means backlight will be on when any button is pressed or reading
changes). Press TARE/UNIT button to choose the backlight mode and press ON/OFF/ZERO
button to confirm and save this setting.
