Electronic Analytical Balance

Operation instruction
2-1 Display instruction
(1)Preparation
*unpack the box and removing all packing,install the pan
*place the balance on a stable work surface,free from vibration,sunshine and air flow
*20℃±2.5℃ for first class balance with a fluctuation of temperature not greater than 1C/h
*relative humidity:first class balance 50%-75%
*working voltage:100-240V 50~60HZ 0.5A
(2)Operation
*check level indicator before use it,if bubble is not in center,adjust the level feet and make it in
center *balance uses touch button,can carry out multiple keyboard control,operation flexibility,can
press corresponding button for conversion and select each function simply.
(3)Power on
A:External calibration balance
*after plugin,the balance start electrify,normally power on the display and start operation after warm
up the machine.
*press power to let display on,the display will show all symbol,after 2 seconds,will show the max
weight on the display,then it will enter weighing mode:0.0000g,press OFF button again for power off
B:Internal calibration balance
*after plugin,the balance start electrify,turn on the balance, the display will start warm up(30
minutes),it will auto-calibration once warm up finished.You could start weighing after displaying
0.0000g.
*for an urgency use.Power on and press the“ON”button again in the warm-up time.It will auto-cal
and you could start weighing after displaying 0.0000g on the screen.
(4)Calibration
The high accuracy analytical balance with two kinds of style: automatic internal calibration and
external calibration
A:Automatic Inter-cal balance
Method 1:
When the balance is displayed as 0.0000g,press the“CAL” button.When the display shows“CAL
INT”,release the “CAL” button.The balance enters the automatic internal calibration state and
displays“CAL”.Waiting for a dozen seconds and the calibration is over.The balance shows 0.0000g
and the balance returns to the weighing state.
*For quick enter the weighing mode
1.Turn on the scale by press the button of“ON”,normally it will automatic start to warm up
30minutes.When it in warm up state,the display will appear t-00-01(02/03/04…), in this state,press
the button of“ON”,then press the “TARE”button,after a few seconds,the 0.0000g will show on the
display,then you can start weighing.
2.When the scale in the sleep mode,the display will show“Close”if you want quick enter weighing
mode,press the button of“ON”,the screen will display “INT-CAL“,after it disappeared,it will in the
state of“.”,then press the button of “TARE”,after a few seconds,the 0.0000g will show on the
display,then you can start weighing.
Method 2:
External-cal(Calibrate with calibration weight)
Pressing the button of “ON”and “CAL”in the same time. The screen will display “--CAL—“and please
wait a few seconds until the calibration weight value to be displayed. Place the corresponding value
weight on the weighing pan and wait for the value displayed stable,then remove the weight and
calibration finished.
*Noted:In normal use,the balance should be calibrated using internal calibration
B:External calibration balance
*long press Cal button until the display show CAL
*place corresponding value weight on the pan which shown the display
5
*remove the weight,then the calibration is finished.
(5)Unit conversion
Long press Unit button and the unit will show on display, choose the unit you want for weight
(6)INT adjustment
*four molds can be choose
INT-0 Fastest
INT-1 fast
INT-2 slow
INT-3 slowest
(7)Stabilization adjustment
four molds can be choose
ASD-0 best
ASD-1 better
ASD-2 good
ASD-3 normal
(8)Counting function
The items used for counting must be standard parts, individual unit weight difference should not big
*four molds can be choose
---Cou-05 ---Cou-10
---Cou-15 ---Cou-20
*long press PCS button,and the display will show“5”
“10” “15“20”in turn,then put the goods to be counted onto the weighing pan,the quantity must same
as the display showed,then press CAL,it will appear the line “---“,after several seconds,it will show
the weighing number on the screen,take out the weighing product and zero will shown on
display,then you could counting the same goods with the quantity you want.
(9)Weighing
*power on enter weighing mode
*after calibration,the weight show in display is the weight of weighing objects.
(10)Tare
*put the container on the pan,it will display the weight value *press TARE until zero show in
screen,put the weighing objects in the container to weight the net weight.
