It is widely applied in numerous fields such as industrial production, commercial trade, logistics transportation, and laboratories, providing users with accurate and stable weight measurement data.Precise Weighing: Equipped with high-precision weight measurement capability, it can quickly and accurately obtain the weight value of the object being weighed, meeting the weighing accuracy requirements of different scenarios.Tare and Zeroing: Conveniently remove the tare weight of containers, trays, etc., so that the measurement result is only the net weight of the goods; at the same time, it supports zeroing operations at any time to ensure the accuracy of the measurement starting point.Cumulative Function: Can automatically accumulate multiple weighing data, facilitating the statistics of the total weight of goods within a certain period of time or multiple batches.Peak/Valley Value Recording: Can record the maximum weight value (peak) and minimum weight value (valley) during the weighing process, suitable for applications that require monitoring the weight fluctuation range.Data Storage and Query: Built-in storage function, capable of saving a large amount of weighing data, allowing users to query historical records at any time, facilitating data traceability and analysis.Alarm Function: Can set upper and lower limit alarm values for weight. When the weight of the object being weighed exceeds the set range, the instrument will issue an alarm through sound and light, alerting the operator to pay attention.Communication Interfaces: Equipped with multiple communication interfaces, such as RS232, RS485, Ethernet interface, USB interface, etc., facilitating data transmission and interaction with computers, printers, PLCs, and other devices, achieving automated control and data management.Product ParameterParameter CategorySpecific ParameterPower Supply- DC Power Supply: 5VDC ±10%- Battery Voltage: 3.7V lithium batteryPower Consumption<4W for DC power supply, typical value: 1W (with one sensor connected)Insulation Performance- Insulation Resistance: ≥100MΩ (based on 500V DC MEGA)- Insulation Strength: 2000V AC (test condition: 50/60Hz, 1 minute)Anti-interference- IEC61000-4-2 (Electrostatic Discharge): Level III- IEC61000-4-4 (Electrical Fast Transient Burst): Level III- IEC61000-4-5 (Surge): Level IIIProtection ClassStainless steel IP65 (front panel protection) (GB/T42-2008)Operating Environment- Temperature: -10°C - 40°C- Humidity: 35 - 85% R·H- Installation Position: No condensation, within 2000m above sea levelSensor InputDC ≤ ±2V, 200mA (MAX)Input Impedance>10MΩZero Point Adjustment Range0 - 5mVGain Input Range1 - 10mVConversion MethodSigma - DeltaWeight Update Rate30 times/secondNon - linearity±0.003% F·S (when the sampling rate is 15sps)Gain Temperature Drift<10ppm/°C (When connecting a sensor, a matching terminal accessory must be used, otherwise the accuracy will drop by 2000ppm)Maximum Display Accuracy1/100000Number of Divisions100 - 100000Input SignalMatched with 4/6 - wire strain gaugesSensor Load CapacityUp to 4 analog sensors of 350 ohmsFAQⅠ.
