GENERAL & SAFETY INFORMATION

• **** 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

PACKING LIST

• Scale
• Manual
• C9V 600mA Power Adapter

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.

DISPLAY CHARACTERS

ONTROL PANEL

FUNCTION KEYS

Sets display to zero
| Long Press: (when on)| Power off the scale
Short Press| Tare a weight
Long Press| Switch between unit of measurement

OPERATIONS & SETTINGS

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 self-check will run, show the version number “**002**”, display full capacity e.g. “F15.000kg”, 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 “ 0——” or “0—— ”, then 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.
WAVE TARE
This device uses a light sensor to allow users to tare the scale with a hand wave, without actually making contact with the scale. Wave tare sensitivity is set to a default setting of 5, but the sensitivity can be increased or decreased on the screen using the Parameter Setup instructions below. There are 8 levels of sensitivity that can be selected. The higher levels are more sensitive and require less distance between the sensor and a user’s hand to tare the scale.
PARAMETER SETUP

1. In normal weighing mode, press and hold ON/OFF and TARE keys until the scale displays “SETUP”.
2. In parameter setup mode, press TARE key to change the setting, press ZERO key to confirm.

0 = no auto-off;
01-9 minutes auto-off time.| 5
| Backlight on-off mode selection:

CALIBRATION

1. Prepare standard weights, and make the scale with no load.
2. When the scale is off, press and hold down TARE/UNIT button, and then press ON/OFF/ZERO button at the same time until appears. Release the two buttons.
3. Be sure no weight on the scale, and press ON/OFF/ZERO button, 0 in CAL-0 will be flashed.
4. When is displayed, press and hold TARE/UNIT button to choose the unit (kg or lb) of standard weight in calibration; load full capacity weight on the platter. Then press ON/OFF/ZERO button, F in will be flashed.
5. When appears again, remove the weight from the platter, and then press ON/OFF/ ZERO button. ” in will flash.
6.  When calibration has been completed properly, the scale will reset to normal working mode. If displays, that means there is an error in calibration, and needs to be re-calibrated.
7. In step 3-5, press and hold ON/OFF/ZERO to exit during the calibration mode.

AUTO-OFF AND BACKLIGHT SETTING FUNCTION

1.  When the scale is on, press and hold TARE/UNIT and ON/OFF/ZERO buttons till SETUP is displayed, then the “
   _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 off to save battery power, when x=0, means no auto-power off function). Now, press TARE/UNIT button to choose the auto-off time and press ON/OFF/ZERO button to confirm and save the setting.

2. The scale will display “BLT.X” (x=0, 1, 2. 0 means backlight always off, 1 means backlight 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 the setting.
