OPERATION OF THE BALANCE
Choosing the Installation Site
The measuring performance of the balance is greatly influenced by the environment
where it is installed.
Observe the following points to ensure safe and accurate weighing.
Precautions on Use
Avoid locations where the balance will be exposed to any of the following.
¤Air flow from an air conditioner, ventilator, door or window
¤Extreme temperature changes
¤Vibration from surroundings or nearby equipment
6
Unpacking and Inspection
Check that all of the items indicated below are included in the package, and that
nothing has been damaged.
[1] Main Body
[2] Pan
[3] Introduction Manual
[4] Cable
[5] Weight for option.
¤Direct sunlight
¤Dust, electromagnetic waves or a magnetic field
Install the balance on a strong and stable flat table or floor.
Placing the balance in an unstable site could lead to injury or trouble with the balance.
When selecting the installation site, take into account the combined weight of the
balance and the item to be weighed.

Turning the Power On
1 Insert the plug of the Power Cord of the balance. (And please pay attention of the
voltage 110V or 220V).
2 Connect the Power Cord to the power outlet.
3 Press “ON”.
The display will automatically go through the changes indicated below.
* If it can not enter above display, please contact with your distributor or your
transportation agent so that they can make the claims in the correct time limit.
* If the above display is unstable or the weighing value is unstable, pls refer to the
[FAILURES AND SOLUTIONS].
Warming Up
Before performing calibration on the balance or measuring its accuracy, you must
ensure that is it in a stable state.
When stabilizing the balance, it is important that its temperature is stable.
Putting the balance in weighing mode and leave it with the power on at least 15
minutes in advance of calibration.
This is called “warming up”.
Performing Calibration
Always perform calibration for a balance after moving it. M1 or higher class weights
are required for external calibration balances.
Before performing calibration, warm up the balance in advance.
Also, carry out the adjustment at a location where there are few people moving
around and there is no air flow or vibration.

prompt value, and operate in turn until the balance automatically returns to zero
after removing the weight.
Convert Units
Balance as a measuring instrument, in order to meet the weighing requirements and
standards of various regions and industries, the balance has a multi-units for option.
The default unit is "g". Short press “UNIT” key to choose the different unit.
Zero
When the weight of the weighed object is not more than 2% of the total range, press
“
TARE/CAL
” key and the balance will return to zero. At this time, the
[
zero

indicator on the display will light up, and the balance can still be weighed in full
range.
Tare
When the weight of the weighed object is greater than 2% of the total range, press
“
TARE/CAL
”, and the balance will return to zero. At this time, the
[
tare
]
indicator on
the display will light up, and the balance can not be weighed in full range. You should
check the balance on the loading progress bar and weigh in the remaining range.
