1. Model specification and index

Model	Specification	Readability	size of weighing tray
BBAL-210, BBAL-211, BBAL-212, BBAL-213, BBAL-214, BBAL-215	0-3100 g	0.01g	Ф130mm

2. Working Condition

Working Temperature: 0°～40°C
Maximum Consumed Power: 5W
Temperature Fluctuation: 5°C/h
Power Supply: 110v-220v,50hz/60hz
Comparative Humidity: 50﹪～85﹪

3. Operation Requirements

When it is operated, electronic balance shall be placed on stable working platform to avoid the influences from mechanical vibration, direct sunshine and air current etc.

4. Operation

(1) Power-on
(2) Switch on the power supply behind the balance and the display indicates in turn “8.8.8.8.8.8.” “Max weighing capability of balance”, “=, =, =, =, =”. At last it shall display the weighing mode as “XXX.XX”. If any error founded in display, you may turn on and turn off the balance once more. Then it will be operated normally.

5. Calibration

(1) Calibration Requirements
When distinct errors appeared in the weighing of balance, the balance shall be recalibrated to make weighing accurate. The recalibrated balance shall be placed on the stable working platform without the influences from the vibration of air current and strong electromagnetic wave. The calibration results will be more accurate 20 minutes later after the balance is operated.
(2) Calibration Procedure
One-point Calibration
Turn on the balance it shall display the weighing mode as “0.00”, then press the “Tare”
button until shows “CAL”, then release. Display blinkingly the stand weight value and then
place same value standard weight; The “= = = = = =” will be displayed; then display stably
weight value and remove weight. then “= = = = = =” will be displayed. the “0.00” will be
displayed;. The calibration is finished.
Three-point Calibration
Turn off the balance, then press the “COU” button and turn on the balance simultaneously
until the display shows “CAL”, then release. The calibration procedure shall be undertaken
as blow:
Display blinkingly the first point stand weight value and then place the same value
standard weight;
Display stably weight value and then remove weight. The “= = = = = =” will be displayed;
Display blinkingly the second point stand weight value and then place the same value
standard weight;
Display stably weight value and then remove weight. The “= = = = = =” will be displayed;
Display blinkingly the third point stand weight value and then place the same value
standard weight;
Display stably weight value and then remove weight. The “0.00” will be displayed;
The calibration is finished.

6. Weighing

(1) Turn on the balance to make it warm up stably and display “0.00”.
(2) Place a thing on the weighing tray and display the weight of the thing. It indicates the
weight is already stable when the display value is not changed again.

7. Tare

(1) If there is a container on the weighing tray, the balance displays the weight of
container.
(2) Press “TARE” and then “0.00” will be displayed. It indicates that the tare has been
deducted.
(3) Place the thing into container and the balance will display the weight of thing.

8. The counting operation of balance

(1) Press “COU” button and “COU” will be displayed. Then display blinkingly one of value of counting mode, “5,10,20, 40, 50, 100, 200, 300, 400, 500” Press “TARE” and choose
one mode value. Place the things with same quantity with mode value on the weighing tray
and then press “confirm” button”. Then “= = = = = =” will be displayed. Very soonly, it will
display stable mode value and then the setting of counting operation is finished. After that,
counting operation could be conducted. Place the things in the weighing tray and display
will show the quantity of thing.
Counting operation requires the weight of weighed thing must heavier than the four
times of minimum reading value or the difference of counting could be great if not
counting can’t be done.
(2) Quit the counting operation:
Press the “COU” button and then “= = = = = =” will be displayed. The balance may quit
counting operation state immediately and return the weighing state.
(3) Overload warning
When weighing thing is over the maximum weighing value of the balance, the
display will show “- - - - - -” and indicate the thing is overloaded. The weighing thing
shall be removed to avoid damaging the balance.
8. Cautions
(1) Switch on power resource according to requirements to make balance warm up
before usage.
(2) Working environment and conditions shall conform to the environment requirements.
(3) The weight of all weighing things on the weighing tray can’t exceed the required
weighing range.
(4) When weighing is not accurate, calibration shall be undertaken by use of standard
weight according to concerning requirements.
(5) If user found any defection in the balance, don’t try to disassemble the machine shell
and repair it to avoid damaging the precision parts in the machine. Please take it to
the distributor or send it to the manufacturer and let them repair.
