SAFETY PRECAUTIONS

• To avoid damaging the battery do not keep charger plugged in once battery is fully charged

• Avoid installing the balance in direct sunlight. This may cause poor performance or malfunctions.

• Do not mix batteries, replace all 4 batteries at the same time

• If the balanced will not be used for a long period of time, remove all batteries from the battery compartment to avoid leakage, which may cause damage to the instrument

• Avoid overloading or dropping material onto the platform as that may damage the balance

• Place the weight on the center of the pan for accurate weighing

• Make sure the weight is not over the Max capacity as it could damage the load cell inside.

• Do not spill liquids on the balance as it is not water-resistant. Liquids may damage the case and any liquid inside may cause damage to the electronics

• Material that has a static electric charge could inuence the weighing. Discharge the static electricity of the samples, if possible. Another solution to the problem is to wipe both sides of the pan and the top of the case with an anti-static agent

• Strong magnetic elds and static electricity will have an adverse effect on the weighing sensor, when the disturbances disappear the machine will function properly again

• Do not modify this machine without authorizing with manufacture

• Do not open the machine housing. Machine will lose its guarantee service is security label is broken

PREPARATIONS & SET UP

• Place your balance on a at, stable and level surface that is free of vibration and drafts and free from corrosive and strong magnetic elds as

they have adverse effects on the weighing sensors

• Level your balance by adjusting the feet to center the bubble in the spirit level

• Do not put machine close to the central heating, sunshine, airow, opening door or window

• Do not expose machine to extreme heat or cold. Keep scale in a clean, dry location because dust, dirt and moisture can accumulate on the weighing sensor

• Plug into a wall outlet to avoid interference with other wirings

• Turn on the balance while there is no load on the pan

• Allow scale to warm up for 1 minute before use

• Calibration may be required before weighing when the balance is initially installed or moved from a location

• If the balance is moved from a place with a difference in temperature, please allow the machine to adjust to the room temperature for 2 hours before use

KEY EXPLANATION

Powering On

• Turn on the power by pressing the button located under the scale’s

screen. Once on, the scale will ash the maximum capacity then enter

the weighing mode and display “0”

• Press and hold MENU for 5 seconds to enter the settings mode

• Press and hold MENU for 1 second to save and exit settings mode

Calibrate / Zero (Enter Key)

• Short press CAL to zero the scale in weighing mode

• Press and hold CAL for 5 seconds to enter the calibration mode

• In settings mode short pressing changes the sub menu

• At the last menu, pressing CAL will conrm the present status and return to either the previous menu, or enter into a weighing function (such as density, dynamic)

Unit (Move Key)

• To switch between measuring units

• Move the cursor (ashing digit) to the left

• When all digits ash press UNIT to change to a single digit ash

Print (Cycle Key)

• When manual printing mode, press PRINT to send weighing data to the printer or computer

• In settings mode when a single digit ashes it will increase the value

• In settings mode when the display ashes it cycles to next parameter

Tare (Return Key)

• Tare

• In settings mode: return to the previous menu without save

• Press and hold PRINT for 1 second to exit from a weighing function (such as density or dynamic)

CALIBRATION

When to calibrate

• When the scale is initially installed

• When the scale’s location has changed

• After the scale has not been used for a long period of time

• If ambient temperatures have changed greatly

How to Calibrate (Span)

• Press the power button to turn the scale on

• When there is no weight on the pan hold the CAL key for about 5 seconds

• When display shows “-CAL-”, release the CAL key

• The display will ash the exact weight needed to calibrate

• Place exactly the required weight on the scale

• When the display stops ashing unload calibration weight

• “---” will be displayed briey to indicate the completion of span calibration

• The display should show 0

• Place your calibration weight on the scale. If the scale reads the same value the calibration has succeeded. If not please repeat calibration process.

How to Linear Calibrate

• Linear calibration

• Verify the pan is empty

• Press the CAL (calibration) key for about 5 seconds to enter into calibration mode. When display shows “-CAL-”, release the CAL key

• Press and hold the MODE key for about 5 seconds, and the blinking number indicates what weight should be placed on the pan

• Load the indicated weight, and wait for the display to stop blinking (scale has recorded this linear value)

• Unload the weight

• Wait for the next blinking number to indicate what weight to place on the pan

• Load the indicated weight, and wait for the display to stop blinking (scale has recorded this linear value)

• Unload the weight

• When the display shows “0.000”, it means the linear calibration is completed

OPERATING INSTRUCTIONS

Preparation:

• Turn machine on

• Allow to warm up for ve minutes

To weigh:

• Add weight to the scale, the display will show result

• Use the unit key to change between units

To tare:

• The Tare function is used when you only wish to see the current change in weight, not the entire amount of weight that is on the scale

• Example: Put a container you wish to use on the pan, then press the TARE key and the display will show the tare symbol and reset back to 0

• Add your sample to the container to weigh without the weight of the container

• To exit Tare mode simply press TARE Note: If you remove your container the scale will show the minus weight of the container

To count:

• The counting function is used to count a high volume of identical parts. You can do this by setting a sample and then either adding to the sample or taking away from the sample to count the number of objects on the scale

• This function can calculate the quantity with total weight divided by signal weight

• Press and hold MENU until the screen reads

• Press CAL to enter and the screen will read

• Press CAL again and the screen will read

• Press CAL again to display the sample quantity ex.

• Press PRINT to cycle through sample quantities and select

• To set the quantity manually: Press UNIT to move the cursor to the left and the PRINT key to increase the number value

• Press CAL to select

• The display will show the results

• Upper left displays the quantity: 20pcs

• Upper right displays the unit weight: 0.11g

• Main window displays the total weight: 2.200g

• Remove samples from pan, the display will show

• Place an unknown amount of pieces on the pan and the scale will count (Example: put 100pcs, total weight 11g)

• To exit counting mode pres and hold TARE key
