The US-5011 Indicator is a versatile weighing device designed for various industrial and commercial applications, emphasizing precision and user-friendly operation. Manufactured by USA Measurements, the device aims to "Outmeasure the Competition" through its robust features and reliable performance.
Function Description:
The US-5011 Indicator primarily functions as a digital display and control unit for weighing scales. It processes signals from a load cell to provide accurate weight readings in both pounds (Lb) and kilograms (Kg). The indicator supports normal weighing, taring, zeroing, and dynamic weighing (hold function). It also offers extensive configuration options for calibration, display resolution, zero tracking, digital filtering, and serial communication, making it adaptable to a wide range of weighing environments and requirements.
Important Technical Specifications:
- Display: The indicator features a clear LCD/LED display that shows weight readings, unit of measure (Lb, Kg), and status indicators (Zero, Net, Hold). It supports a maximum display of 6 digits.
- Capacity and Division: The device supports a broad range of capacities and divisions, configurable through parameters C1 to C5. For instance, the main weight unit can be set from 100 to 20000, with a second unit (if applicable) from 100 to 25000. Division selections include 0.1, 0.2, 0.5, 1, 2, and 5. Decimal point positions are configurable (e.g., 0-x1, 1-x0.1, 2-x0.01, 3-x0.001, 4-x0.0001, 5-x10).
- Weight Units: The primary weight units are Lb and Kg, with configurable display division values for each. For example, a 0.0001kg division can correspond to 0.0002lb, and a 0.0001lb division can correspond to 0.0005kg.
- Zero Range: The ZERO/ON/OFF button's zero range is highly configurable (C8), from ±1%FS (Full Scale) to ±100%FS, or no limitation. This allows for flexible zeroing based on application needs.
- Power-on Zero Point: The indicator can be configured to use the current weight, calibration zero point, or power-off zero-point as the initial zero when powered on (C9, C10).
- Zero Tracking Range: Adjustable from no tracking (0) to ±6d (9), allowing the indicator to automatically maintain zero within a specified range (C11).
- Digital Filter Intensity: Offers four levels of digital filtering: very weak (0), weak (1), middle (2), and strong (3) to stabilize readings in noisy environments (C12).
- Motion Check Range: Configurable from ±0.25d (0) to ±7d (9) to determine when the scale is stable for accurate readings (C13).
- Max. Weight Display: Allows for displaying weights beyond the nominal full scale, up to 200%FS, or no limitation (C14).
- BMI Function: Can be enabled or disabled (C15).
- Serial Communication: Supports RS232 and USB output. Configurable baud rates (U6) include 1200, 2400, 4800, 9600, and 19200. Data formats (U7) include 8N1, 7O1, and 7E1. Output formats (U5) range from disabled communication to continuous output of stable weight, gross/tare/net weight, and status data, or command-response mode.
- Power Supply: Operates with an AC adapter.
- Operating Temperature: Not explicitly stated, but implied to be suitable for typical industrial environments.
Usage Features:
- Keypad Functions: The indicator features a straightforward keypad with dedicated buttons for common operations:
- HOLD/SETUP: Sends output data (short press) or enters/exits HOLD mode (long press). In setup/calibration, it shifts the flashing data entry position.
- PRINT/FUNC: Sends output data (short press) or enters/exits HOLD mode (long press). In setup/calibration, it shifts the flashing data entry position.
- ACC/TOTAL: Accumulates weight or accesses totalization functions.
- UNIT/DATA: Selects the weight unit (Lb/Kg) (short press) or increases the digit in data entry (long press).
- TARE/PRESET: Tares the weight (short press) or confirms input data and proceeds to the next step (long press).
- ZERO ON/OFF: Zeros the platform weight (short press) or powers off the scale (long press). In setup/calibration, it exits to normal weighing mode.
- ZERO ON/OFF + UNIT (long press): Enters USER parameter setup mode.
- ZERO ON/OFF + TARE (long press): Enters calibration mode.
- Normal Weighing Mode: Simple operation: power on, place objects, read weight. The display indicates "Zero" when the scale is zeroed, "Net" when displaying net weight, and "Hold" (flashing or steady) during dynamic weighing.
- Setting a Tare Weight: Place an empty container, press TARE. The display shows net weight, and the "NET" annunciator lights up.
- Calibration: The manual outlines a detailed calibration procedure involving zero-point and span calibration. It supports standard weights (more than 10% of FS weight) and allows for multi-point calibration (up to three points). The indicator provides feedback on calibration success or error.
- User Parameter Setup: Accessing this mode allows users to customize various operational settings, such as auto-off time (U1), backlight options (U2), hold function key settings (U3), and stable weight reading criteria (U4).
- Serial Communication: The indicator can output stable weight, gross/tare/net weight, and status data via USB or RS232, either on demand (PRINT key) or continuously, depending on the U5 setting. This facilitates integration with external systems for data logging or control.
- Error Codes: The display shows specific error codes (e.g., "Ad----", "CAL.Er", "EEP.E1") to indicate issues like overload, calibration errors, or parameter corruption, aiding in troubleshooting.
Maintenance Features:
- Troubleshooting Guide: The manual includes a comprehensive troubleshooting section that addresses common issues such as the device not turning on, "Ad" errors, "0" errors, overload/underload indications, and inaccurate weighing. It provides probable causes and recommended remedies, including checking connections, replacing batteries, recalibrating, or returning the scale for repair.
- Parameter Recovery: Parameter C16 allows for recovering all parameters to default settings, which can be useful for resolving configuration-related issues or resetting the device.
- Configuration Settings: The extensive configuration parameters (Cxx and Uxx) enable technical users to fine-tune the indicator's performance and address specific application needs, effectively serving as maintenance and optimization tools.
- Load Cell Diagnostics: Error codes like "Ad----" and "Ad-----" point to potential load cell or cable issues, guiding maintenance personnel to inspect these critical components.
- Zero Calibration: Regular zero calibration is a key maintenance step to ensure accuracy, especially after moving the scale or if the zero point drifts.
- Weight Calibration: Periodic weight calibration with known standards is essential to maintain the accuracy of the scale over time and compensate for any drift or wear in the load cell.
