PBJ only: Internal automatic calibration in response to temperature changes or time-controlled at defined intervals. PBS only: CAL calibration program for setting accuracy, external test weights available for an additional charge. Metal housing: Robust and stable. Dispensing aid: High stability mode and other selectable filter settings. Weighing with tolerance range (test weights): Input of upper/lower limits. An optical signal supports portioning, dosing, and sorting. Convenient summation of individual weighings. Easy formulation/documentation with combined tare/print function. Additionally, the ingredients of the formulation are automatically numbered and printed with their number/weight value. Identification number: 4 digits, user-programmable, printed in the calibration protocol. Automatic data transfer to PC/printer after each stability of the scale. Draft shield as standard equipment, for models with readability d = 0.001 g, weighing chamber WxDxH 180x193x87 mm.
