Operation RequirementsⅢ
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.
OperationⅣ
(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.
CalibrationⅤ
(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 2 minutes later after the balance is
operated.
(2) Calibration Procedure
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 stably weight value and then remove weight. The “= = = = = =” will be displayed;
Display blinkingly the third point stand weight value and then place same value standard
weight;
Display stably weight value and then remove weight. The “ . ” will be displayed;
The calibration is finished.
Weighing Ⅵ
(1) Turn on the balance to make it warm up stably and display “ . ”.
(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.
TareⅦ
(1) If there is a container on the weighing tray, the balance displays the weight of container.
(2) Press “TARE” and then “ . ” 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.
The counting operation of balance Ⅷ
(1) Press “COU” button and “COU” will be displayed. Then display blinkingly one of value of
counting mode, “5,1 ,2 , 4 , 5 , 1 , 2 , 3 , 4 , 5 ” Press “TARE” and choose one
mode value. Place the things with quantity same with mode value on the weighing tray
and then press “confirm” button”. Then “= = = = = =” will be displayed. Very sonly, 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 o f minimum reading value. Or the difference of counting could be great or
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.
Ⅸ 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.
