• 4 Optional Setpoint DO Output Modes: Weight Limit DO Alarm Mode, Weight Increment DO Output Mode, Weight Decrement DO Output Mode and Weight Section DO Output Mode.
• EMC design with high anti-jamming capability, suitable for industrial environment.
• 32-bit ARM CPU with 48MHz clock & higher arithmetic speed.
• 5 Red LED digital tubes for English character and digit display.
• Menu&Shortcut mode operation.
• 24-bit High-precision and high-speed ∑-△A/D conversion module with 1/1,000,000 internal resolution and sampling frequency 1280Hz.
• Special anti-vibration digital filtering algorithm for ensuring the weighing stability and accuracy when there is strong vibration on the load receptor, and the rapid response capability when the weight signal changes.
• Optional weighing input signal mV, V and mA for connecting ‘【mV】Output Type Loadcell’, ‘【V】Voltage Output Type Weighing Transmitter’ and ‘【mA】Current Output Type Weighing Transmitter’.
• Auto Zero Initial Calibration after Power-on, Auto Zero Tracking, Zero Fine Adjustment, Zero Calibration and Load Calibration functions available.
• Optional Data Calibration, Segmenting Span Correction and Segmenting Weight Calculation functions.
• Auto-locking, Key-locking, Key-unlocking, Digital Setting&Calibration and I/O Testing functions available.
• 2 Relay switches with normally open and normally closed contacts for outputting upper limit and lower limit alarm signals.
• 1 Optional and definable analog signal output [AO: 0~20mA].
• Optional RS232 and RS485 communication ports for connecting Host IPC/PLC and LED Remote Display.
• With the multitasking mode, the processes of weighing, alarm output and signal transmission will not be interrupted by parameter setting and the other operations.
