Page 4: Chapter 1 Brief Introduction
Chapter 1 Brief Introduction 1. Basic Operating Principle of Digital Load Cell Digital Load cell system is a brand new electronic weighing appliance developed from the traditional strain gauge sensor by using modern micro-electronics technology and micro-computer integration. It includes two parts, analogue load cell (strain gauge) and digital converter module. Converter module is a high-integrated electronic circuit and adopts SMT on the surface. - Page 5 diagnosing is easy. E. High flexibility All communication via standard communication interface RS485. It is connected to PC directly or other standard industrial mastering bus. It is easy to use and build the scale. F. High security, to avoid cheat function It can prevent remote controller cheating.

Page 18: Chapter 6 Calibration
Chapter 6: Calibration When indicator is packed before leaving factory, there is also a 15 pins RS232 plug, called calibration plug which is used to set the related coefficient between the indicator and load cells. When the indicator is working, the calibration plug should not be plugged in. Any time when the plug used, following process should be adopted. - Page 19 Steps Operation Display Note The Calibration plug has been plugged in Press under weighing state.

of the platform share a greater weight. This proportion is about 2：1. In order that the platform shares a uniform force, we require the ISN max. Value minus min. value of the four load cells on margin less than 400; Likely the max. ISN value minus min. ISN value of the four load cells in center less than 400.(If the scale has 8 load cells, then there are 4 load cells in the center). -

Chapter 10: Operation 1. Start-up & Automatic-zero setting at start-up Power on. The indicator will be under measuring status after self examination from ‘000000’ to ‘999999’. After start-up, the device will compensate for small changes in zero if the value is not zero but still in the zero range (±4% ±10% ±20% ±40% ±100%F.S are optional) ‘Deduct Tare’... - Page 30 Vehicle number must be a value between 00001 and 99999. That is to say 0000 is not a legal vehicle number. If the number is 00000, the third method is adopted to weigh the goods. If the tare is known already, one time testing is enough to have the full record.

Possible Reason: Maybe the fuse is broken, or no power source, or the transformer inside crashes because of high voltage. Solution: Change a new fuse, check the electricity, or check the transformer. 2.
- Page 33 Turn the indicator off, plug in the address modifying plug, and connect the sensor to the indicator (they can only be tested one by one). Power on, the code of the sensor will be displayed after self examination. Press ENTER, the load value will be shown according which we can indicate whether the sensor is ok or not (find detailed information in section 7).
- Page 34 14. Malfunction description: It gives a big number after booting, and it jumps in a wide range. Possible reason: unstable voltage or environmental interfere Solution: strengthen the stability of electricity and earth the device. Test the voltage of the metal cover if it has, earth the cover if necessary. 15.
