1. Introduction
This manual is taking LD5100-1 as an example to explain how to use the balance. The features: l Super large LCD screen display, it is clear and easy to be read l Fast weighing, the speedof weighing is from a dozen times to scores of times faster than general mechanical balance l It is easy to operate, weigh directly l High intelligence: within the weighing range you can tare, zero clearing and accumulated weighing; over loading display and fault alarm l Built-in hanger for below-balance weighing (Optional choice) l Malfunction, such as ct and oz units exchange, piece counting,percentage weighing etc. l In order to print the weighing data off through the printer or input the data to computer or other external devices, the comparator can have the optional choice of RS-232 interface.
