The **TCS-65-R** refers to a high-precision, industrial-grade **Electronic Platform Scale**. These devices are designed for heavy-duty commercial weighing applications, integrating precision electronics with robust mechanical structures. --- ### 1. Core Electronic Components The functionality of the TCS-65-R is driven by several key electronic sub-assemblies: | Component | Description | Function | | :--- | :--- | :--- | | **Load Cell** | High-precision strain gauge sensor | Converts physical weight (pressure) into an electrical signal (millivolts). | | **A/D Converter** | Analog-to-Digital Integrated Circuit | Translates the analog voltage from the load cell into digital data for the CPU. | | **Microcontroller (CPU)** | Central processing unit | Processes digital weight data, handles tare calculations, and manages the user interface. | | **Display Module** | LED or LCD Screen | Shows weight, unit price, and total price (often featuring high-brightness green or red digits). | | **Power Management** | AC Adapter & Rechargeable Battery | Allows the unit to operate on 220V/110V mains or a 4V/6V lead-acid battery for portability. | --- ### 2. Technical Specifications (Electronic) The "65" in the model name typically indicates a maximum capacity of **60kg - 65kg**. * **Accuracy Class:** OIML Class III. * **Resolution:** Usually 1/3000 FS (Full Scale). * **Input Voltage:** 110V/220V AC. * **Operating Current:** <500mA during active weighing; significantly lower in standby mode. * **Sampling Rate:** 10–40 times per second. --- ### 3. Key Electronic Features The TCS-65-R electronic logic includes several automated software functions: 1. **Auto-Zero Tracking:** Automatically resets the display to 0.00 when small amounts of debris or dust accumulate on the platform. 2. **Tare Function:** Allows the electronics to subtract the weight of a container to show only the "net" weight of the contents. 3. **Power Saving Mode:** Dims the LED/LCD display after a period of inactivity to preserve battery life. 4. **Overload Alarm:** An internal buzzer sounds and the display shows "Err" or "---" if the weight exceeds the 65kg electronic limit to prevent load cell damage. --- ### 4.
