1. INTRODUCTION
The Steinberg Series of electronic price scale are equipped with high precision
load cell as primary instrument, the secondary instrument designed by using new
technology and new materials such as 8951 single-chip microprocessor as main
chip and A/D converted with three-integral or Σ-Δ module conversion.
The Steinberg Systems series of electronic price scale are good products with
reasonable prices. It has functions of overload and under-voltage alarms, auto
and continuous AC/DC shift, power supply identication, price or weight adding
which is according to model. Particularly, it can protect the saved data to ensure
accurate weighing.
