ⅠGeneral
Orthoptic Electronic Crane Scale series consists of hanging pendant, high-precision load cell, A/D converter and display. The high-luminance digital display of 5 bits and 1.2 inch with word height 30mm, which can be read clearly in a remote distance, is full of clearness and brightness. Because this style of crane scale adopts intelligent digital filter which can avoid shaking, vibration and swinging, it has stability of reading with the stability time less than 5 seconds. Meanwhile, it has functions of instant and delayed tare as well as automatic accumulation. Adoption of low power consumption design lengthens the lifetime of the display can continuously work for more than 60 hours. Being equipped with over-discharge protection circuit, it will prevent the battery from damaging and shortening the lifetime due to over-discharge. In addition, the function of automatic shutdown makes the life of battery longer. Battery capacity’s showing (percentage showing) while start-up and shut down will enable you to know the battery capacity timely, thus, you can select proper time for charging.
Orthoptic Electronic Crane Scale series has advantages of high precision, stable ratio of performance/speed and convinence, and is applied for the hosting occasion of foundary circle, warehouses, mines, docks, and factories.
