3. TECHNICAL DESCRIPTION
4. STANDARD OPERATIONS
3.1 Connection of the load cell to indicator
3.2 Connection of RS232 to PC or Printer (optional)
Make sure the equipment connected correctly and parameters set well, and also the scale has already been
calibrated correctly.
Configuration and Calibration - Refer to TECHNICAL MANUAL
!Do not modify it by yourself; consult our distributor or your local authorized metrology worker, wrong
operation may cause the problem or wrong performance of the scale.
4.1 Switch on and switch off
Press ON/T to turn on the indicator
Press OFF for 2 seconds to turn off the indicator
4.2 Zero/Tare
4.2.1 If the display is not 0 after power on, pressON/T to zero the scale (<2%F.S.)
4.2.2 Weighing with the container, put the container on the scale (>2%F.S.) and pressON/T to make a
tare and get subtract of the weight of the container.
4.2.3 Remove the tare: remove the container and press ON/T to clear the tare value and zero the scale.
4.3 BMI Check
When the weight is stable, press BMI key to input the height value (on kg unit, it’s in the unit of cm, on lb
unit display, the height unit is feet and inch), after the height input, press BMI key again to get the BMI
index.
* When it display the BMI value, if you want to back to the weight display, please press  UNIT  key

5. FURTHER OPERATIONS
4.5 Manual Hold
When the weight is stable, press HOLD key to lock the weight and press it again to unlock.
4.6 Print
If the printer connected or PC connected, press PRINT to print the receipt or send data to computer,
and the format as below:
TICKET NO.: 00005
G.W: 78.5kg
T.W: 2.0kg
N.W: 76.5kg
H: 180cm
BMI: 23.6
4.7 Units Exchange
Press UNIT to exchange the weight units
Units set (kg/lb as default) - Refer to TECHNICAL MANUAL
Press BMI key andON/T at the same time, it will display UF - 1 , press ON/T or PRINT to
shift it from UF - 1 to UF - 9 , press BMI to enter and configure it.
5.1 Internal A/D Value and Battery Volume
UF - 1
Press BMI to view the internal A/D value of the scale
Press BMI again to display the voltage of the battery.
Press BMI again to change for next set or press UNIT to quit and back to normal weighing mode
5.2 Hi/Lo/Ok Checkweigh Function
* You can set a ideal weight as you want to achieve and the indicator will beeps if the weight above or low
than the weight you want.
UF – 2 Press ON/T PRINT HOLD to move and change the digits.
Press BMI to set the Lo value (the lower limitation) – 000.00L
Press BMI to set the Hi value (the top limitation) – 000.00h
Press BMI to change the working mode of buzzer of Hi/Lo/Ok – o 000
Remark
o 0 0 0
o A B C
A=0 Stable but no need to buzz
A=1 Stable to buzz
B no function, keep it as default and no change
C=0 Buzzer off
C=1 It beeps when the weight is ok (Lo<weight<Hi)
C=1 It beeps when the weight is out of limitation (Lo>weight or weight>Hi)

5.3 Auto Power Off
UF – 3 Press ON/T PRINT HOLD to move and change the digits.
Press BMI to enter the set of automatic off function– AoFF 00
00 Auto off deactivated
01-99 Auto off activated in 01-99 minutes, you can change it from 01 minute to 99 minutes
5.4 Backlight
UF – 4 PressHOLD to change the digits.
Press BMI to enter the set of backlight function– Lit A
A Automatic
ON Backlight On
OFF Backlight Off
5.5 Auto Hold Function
UF – 5 PressHOLD to change the digits.
Press BMI to enter the set of backlight function– hoLd 0
0 Deactivated
1Animal weighing (refer to below remark)
2Peak hold (press any key to exit except forBMI key)
3Stable hold (press any key to exit except forBMI key)
4Stable hold (exit automatically when the weight is removed)
Remark
When choose hold = 1, it need to set the following two parameters
1. PCt xxx the number is from 001-100, the bigger number means the more accurate weight, but the
weighing time is longer, the smaller number means fast weighing (shorter stabilizing time) but not so
accurate result, it can be chosen depends on the weighing condition of the scale.
2. TinE xthe number it can repeat during the range of hold, it can choose 1/2/4/8/16/32/64
5.6 RS232 Interface (Optional)
UF – 6 PressHOLD to change the digits.
