The DIGI SM-500 series represents a sophisticated line of PC-based scales designed for high-volume retail environments, integrating weighing capabilities with advanced label printing and data management. Core Technical Features The SM-500 series, including the popular SM-500 MK4
, is built for centralized management and detailed retail operations:
Centralized Programming: Key operations such as PLU data programming, preset key assignment, and label format editing can be managed through scale application software like e.Leap.
Advanced Labeling: The scale supports high-resolution thermal printing and flexible label formats, allowing for logos, barcodes (EAN-13, ITF, etc.), and extensive product details like "Sell by" and "Use by" dates.
Hardware Interface: Modern models feature touchscreens for easier navigation and high-speed thermal printers. Operating the DIGI SM-500 Scale
Operation of the SM-500 typically involves three primary modes: Registration, Programming, and Setup. 1. Setup and Assembly
Initial Setup: Assembly involves mounting the display pole and ensuring the scale is level via the adjustable feet for accurate measurement.
Paper Installation: Loading labels involves accessing the side printer compartment, feeding the roll through the thermal head, and ensuring the sensors are aligned for the specific label size used. 2. PLU and Data Programming Programming new items (PLUs) is a fundamental task:
Entry: Users enter a unique PLU number and follow prompts to input the product name, such as "Fresh Salmon".
Pricing: Set unit prices and specify whether the item is weighted (per kg/lb) or sold as a single unit. digi sm500 scale user manual
Secondary Info: Advanced fields allow for ingredients, storage instructions (e.g., "Store at 4°C"), and country of origin labels. 3. Maintenance and Diagnostics
Cleaning: Regular maintenance requires cleaning the thermal print head with specialized cleaning pens or soft cloths to prevent streaking or unreadable barcodes.
Remote Diagnostics: The system supports remote troubleshooting through its networked application software, minimizing downtime for high-traffic retailers. Reference Documentation
Detailed manuals are often available through professional checkout technology repositories:
Service Manuals: Comprehensive guides for hardware testing, maintenance, and motherboard-level repairs can be found on sites like The Checkout Tech.
Operation Guides: For day-to-day user tasks, many retailers rely on digital PDF versions of the SM-500 Programming and Operation Manual. OPERATION MANUAL

High PLU Capacity: Standard memory supports up to 10,000 PLUs (Price Look-Up items), expandable to 10MB for detailed nutritional facts and ingredients.
Centralised Management: Use the e.Leap application to remotely manage PLU data, preset key assignments, and label formats. The DIGI SM-500 series represents a sophisticated line
Versatile Printing: Features a spacious printer compartment for quick label or receipt changes, supporting wider print widths for traceability data.
Security & Diagnostics: Includes password protection, audit trails, and remote firmware upgrades to reduce on-site maintenance. Quick Setup & Programming
Power On: Press the ON/OFF button located on the top right of the display.
Enter Setup Menu: Press the SELECT button (bottom right), followed by holding the FUNCTION button. Programming a PLU: Enter the desired PLU number on the keypad. Press the PLU button.
Enter item details (e.g., name, price) and press enter to save.
IP Address Setup: Change the scale's IP address by adjusting SPEC 135 (typically found under system settings). Calibration Guide For maintenance, the
requires precise calibration using the "Span Switch" and specific key sequences: Locate and press the Span Switch. Press M, Re-Zero, M, and M to enter "Z Mode". Hold Re-Zero and type 8715 to enter Calibration Mode.
Remove all weight from the platter and press the Total Print (*) key.
Place the required calibration weight on the scale and press Total Print (*) again. Wait for the process to finish before removing the weight. Manuals & Resources Grams (g) Carats (ct) – 1 ct = 0

| Error Code / Issue | Probable Cause | Solution | | :--- | :--- | :--- | | "Overload" or Err | Weight on the scale exceeds capacity. | Remove excess weight immediately to prevent sensor damage. | | Label Not Printing | Label roll is empty or jammed. | Open the printer cover. Ensure labels are feeding correctly through the sensor. | | Weight Fluctuating | Air currents or unstable surface. | Ensure the scale is on a flat, level surface away from strong fans or vents. Press ZERO. | | "PLU Not Found" | The entered PLU number does not exist. | Check the PLU list or program the item. | | Price Incorrect | Wrong unit price entered in memory. | Re-program the PLU with the correct price. | | "Tare Error" | Negative weight on the scale. | Remove all items and press ZERO. |

The Digi SM-500 is a high-performance label printing scale commonly used in supermarkets, delis, and grocery stores. It is known for its durability and ability to store a large number of PLUs (Price Look-Up codes). It supports pre-pack labeling and random weight printing.
Press UNIT (or MODE) repeatedly to cycle through:
Note: Precision may slightly vary by unit due to rounding.
Note: Calibration should be done after warm-up, on a level surface, and using certified calibration weights of the correct value.
