This document describes the EXCELL PRECISION CO., LTD. 4th Generation Price Computing Scale, specifically the 20-key Standard Version.

Function Description:

The EXCELL Price Computing Scale is designed for accurate weighing and price calculation of commodities. It features a high-performance A/D converter and linearity calibration function to ensure precision. The scale can display weight, unit price, and total price, and supports accumulation functions for multiple items. It also includes RS232 output for data transmission, making it suitable for integration with other systems. The scale is equipped with a battery for portable use and offers various settings for backlight mode and pricing units.

Usage Features:

• Preparation:
  • Place the scale on a firm, level surface.
  • Adjust leveling feet until the leveling bubble is centered.
  • Ensure stable temperature and airflow, avoiding direct sunlight or ventilating systems.
  • Use an individual socket to avoid electrical interference.
  • Remove any weight from the platter before switching on.
  • Release the protection screw "J" before weighing.
  • Place commodities in the center of the platter, ensuring their dimension does not exceed the platter's.
• Keyboard Functions (20-key Standard Version):
  • 0-9: Number keys for inputting numbers and setting unit price.
  • CE: Clears old unit price; allows immediate input of new unit price if previous price was entered within 3 seconds.
  • T: Deducts container's weight; "T" symbol appears in Weight display.
  • Z: Returns weight to zero.
