Thank you very much for your purchasing BONGSHIN Digital Weighing
Indicator of BS-8300.
This Instruction Manual will lead you to use BS-8300 with top reliability,
High speed, high accuracy.
BS-8300 is Digital Weighing Indicator amplifying the analog output from a
load Cell, converting the analog signal to digital data and then displaying
this data
As a weight reading and is designed for flawless performance in your
demanding
Application of input-weighing, output-weighing, accumulating-weighing,
2step control.
Also, an additional option will make Modern Industry demand equipment
that both versatile
And availed to easily connect to other devices
※ Example for application :
1. PACKING EQUIPMENTS FOR MANUAL WEIGHING
2. EQUIPMENTS FOR AUTO-FILLER WEIGHING
3. EQUIPMENTS FOR OUTPUT WEIGHING
4. EQUIPMNETS FOR ACCURACY WEIGHING
5. RECORD-MANAGEMENT FOR PRODUCT WEIGHT
☞ REMARK
- Specification subject to change for improvement without prior notice.
- If changing, the Version No can be increased, but keeps a former
version
As far as possible

Please keep the following using conditions certainly
■
EARTH
To avoid an electric error such as a noises in your production line
It should be earthed before installation certainly.
Specially it will be safety to divide the power of Indicator into a load cell.
■
SAFTY CONDITIONS
Don’t use it closed to a explosive gas and an inflammable dust
environments
■
POWER
Use the power under 110/220V 50/60HZ ±10% and divide it into the
power line
■
TEMPERTURE CONDITIONS
Operating Temperature : -10o C ∼ +40o C ( +14o to 104
o F )
Custody Temperature : -40o C ∼ +80o C ( -40o to 176
o F )
■
INSTALLATION LOAD CELL
- Available to use the same load cell of 6pcs ( 350Ω standard )
- A ground should be installed horizontal
-Installing over 2pcs of load cell, please connect each line in parallel
and Insert a variable resistor under 50Ω in EX + line and minimize a output
Accuracy of load cell.
It may occur a weight error by each accuracy of load cell.
-
It may occur a weight error in case of a temperature variation of load cell
- Please weld(elect spark) at the place installed with load cell and equipments,
Divide the power into a connector of load cell in inevitable case
-
Please connect the below construction of load cell with the above ones using
The earth to the weighing part weighing a material occurring a electro sparks.

- A compact Appearance by DIN regulations ( DIN 193 x 96 Panel system )
- Easy to preset, change, confirm the weight value by the numeral key.
- Improved a convenience and precision of operating with Message
Function.
- Can use or disuse each key function. (SETUP Reference)
- Weight Memory function even in electro spark case.
- Watch-Dog timer guards for self-diagnostics.
- Set up to 1/20,000 display resolution
- Function available to change the unit value such as g,
kg, ton.
( In case of Serial Communication & Printer )
- Various specification of weight conversion speed.
(Digital Filter Function)
- Various option and addition for customer’s satisfaction such as serial
communication, RS-422, Printer, BCD Input and so on.

Calibration is to adjust max weight, minimum division, decimal point
displayed to Indicator
To the actual weight worked by load cell.

changed.
