PM-LD31 weight indicator is the simplest member of the family of ParsMega weight indicators. This model, like all other products of this family, is equipped with a 24-bit ADC converter, which provides the user with a resolution of 1:100,000 with the help of software and hardware filters.
A row of 6-digit 7-segment display makes it possible to easily read the weight. Also, by having four keys on the indicator, it has created simple access to the menus. The ability to define various functions for keys and digital inputs are significant tools to facilitate the design of weighing systems.
Also, the PM-LD31A model has analog output with very high accuracy and resolution while maintaining all the features of this model.
