Chapter 1 Introduction
1-1 Production Introduction
1. High performance A/D converter
2. According to different resolution to do linearity calibration

Ordinary resolution models (below 10000)
Do specification calibration first then do weight calibration

High resolution models (10000~30000)
Do linearity calibration first

specification calibration

weight calibration at last
3. LCD display with LED backlight, powered by battery or plug-in mains, automatic power-off
function to ensure the stability of the scale. When battery voltage is lower than the system
voltage, scale is automatically powered off to ensure the accuracy and stability of the scale.
4. Check Weighing function for high limit and low limit and OK range.
5. 5 HOLD functions including animal scale HOLD
6. Depending on actual space, a RS232 card and/or a relay card can be installed.
