1 BALANCE SERIES INTRODUCTION
1.1 Introduction
Same appearance, similar to the operation, not the
same sensor module. It contains four series products:
1. FA series electronic analytic balance
Readability: 0.1mg
2. FB series internal calibration balance
Readability: 0.1/1mg
3. JA series electronic precision balance
Readability: 1mg
4. JS series density balance
Readability: 0.1mg/1mg
The basic function of four series balance is almost same; expect special function (such as density measurement).

Different model balance has different calibration weight, please see parameter list at part six.
Please keep packing materials properly for transport
2.2 Install, level Adjustment
Best placed place
For high resolution analytical and precise balance, the right
placed place is the key for accurately weighing. So please
ensure that:
·Stable and no vibration position, as far as possible be level
·Avoid direct sunlight
·Avoid strenuous temperature variations
·Avoid air convection
Best placed place: the corner of shelter, stable table, as far as
possible from the door, window, radiator and the outlet of air
condition
Through regulating the leveling foot, make the level bubble moving to the
center of circle. Please adjust balance in the stable table, avoid the
position of the large air flow, virbration and high rate temperature change.
(as shown)
Notice: Please adjust level, when the balance move to a new place.
2.3 Safety Guidelines/Power
• Do not use the balance equipped with standard AC power in the
damage area.
• Please confirm the power adapter whether is match to your local
volatge before getting through the power.
• The balance can only be used in dry enviroment.
Power connection：
→Plug jack-plug of AC adapter in the socket of balance, another side
connect the power.
→Turn on the power, a buzzer emits beep. The balance could be used.
Notice：The balance should be warmed-up for 60 minutes in first time, to
9
achieve the working temperature, in order to obtain the accurate resultes.
Zero/
CAL/
2.4 Calibration
In order to obtain the accurate resultes, it is need to calibration according to the local acceleration of gravity.
Necessary situations to calibrate the balance:
·Before the first measurement
·After weighing for a period
·Weighing location changed
Should start the balance for 60 minutes before calibration to achieve the working temperature, in order to obtain
the accurate.

·Connet to the power. Keep pressing both the and on the shutdown of balance.
·Balance full – screen displays and displays self-inspection sign, then display
·Page area, line area and word area all display number from “ zero ” to a certain number automatic circulated
·The zero show in page, line or word area means that if now press shortly, the balance will
return to last menu.
·Nonzero digital in page or ine zrea, if press shortly, enter to the next menu.
· Nonzero digital in word area, if press shortly, select setting and showing “V” at same time.

5.3 Balance Setting Funcation Explain
【Adapting the balance to ambient conditions】：Room to place the balance uses ordinary air-condition, generally
select C113. If the air is large, should select C114.
【Ambient conditions Stability range】：If need to weighing quickly, can extend the display range. If the air is
lager,should extend the range.
【Display】：Select your desired mode.
【Remove the container】：Please operate carefully if you select 141.
【Auto zero】：To do measurement ranging from a few to tens of digit around zero, please choose C152, and please
pay attention to drifting of the zero digit, that might affect the precision of the measurement.
5.4 Balance Setting for Quick Weighing
【Adapting the balance to ambient conditions】：Select C111or C112, the speed is more fast.
5.5 Balance Setting for Strong Air Enviroment
Avoid strong air , select C114, C126, C127, C128, C129, C141 or C211.
5.6 Balance Setting for Linear Correction
Balance completely preheating, first to calibraion, then shutdown the balance. Restart the balance, thenenter the
setting mode. Choose linear correction function (C312)

“ ”flickering means that there is nothing on the weighing pan. Press shortly. When send

out voice of “du” and stop flickering, it is means finishing corretion. Then the balance auto turn to the next
correcting point “ ” , it need to add 50g weight. Then press shortly to ensure. After
finishing all the correction point, the balance will display “ ”. Now the balance is still processing the
data, please wait. Finishing data processing, the balance will shut down automatically.
5.7 Recover Factory Setting
If customer need to recovery the factory setting, please enter the balance setting mode when starting. Choose
C313 to recover, then the balance will shut down automatically. Also it need to do linear correction.
