Comprehensive Operation & Programming Guide
To save battery, the scale automatically turns off after 2–3 minutes of inactivity. You cannot disable this on most SM-500 models. Simply press ON/OFF to resume.
Your Digi SM-500 should be calibrated:
Q: Can I use the Digi SM-500 to weigh gold or silver?
A: Yes. Switch to “ct” (carat) or “gn” (grain) mode. For bullion, ensure you have the 0.01g resolution version. Always use calibration before precious metal weighing.
Q: My scale shows different weights if I place the item near the edge vs. center.
A: This indicates sensor damage or overload history. Check that the pan is seated properly. If the issue persists, the load cell is likely bent – contact Digi support.
Q: Can I weigh liquids?
A: Yes, using the tare function. Place an empty cup on the scale, press TARE, then pour liquid. Do not spill liquid onto the scale body.
Q: What does the “STABLE” indicator actually mean?
A: The internal processor requires three consecutive identical readings within the tolerance band before displaying “STABLE”. Lightly touching the table will cause the indicator to turn off.
Q: Why does the scale turn off when I try to weigh heavy items?
A: The auto-protect circuit engages if you approach 500g too quickly. Always place heavy items slowly. Below 490g, it should not shut off.

Comprehensive Guide to the DIGI SM-500 Scale User Manual The DIGI SM-500
is a high-performance PC-based weighing and labeling scale widely used in delis, supermarkets, and industrial food processing environments. Understanding the DIGI SM-500 scale user manual is essential for optimizing its advanced features, which include high-speed thermal printing, wireless networking, and a customizable touch-screen interface.
This guide simplifies the technical documentation to help you set up, program, and maintain your scale efficiently. 1. Initial Setup and Installation
Before diving into the software, ensure the physical installation is correct to maintain weighing accuracy.
Leveling the Scale: Use the adjustable feet to center the air bubble in the level indicator. An unlevel scale will result in "Weight Unstable" errors.
Powering On: The power switch is located on the underside or rear. Allow the unit to perform its initial self-test and zero out ( 0.0000.000 ) before placing items on the platter.
Loading Labels: Open the side printer cover. Slide the label roll onto the spindle, thread it through the thermal print head sensor, and ensure the backing paper is secured to the take-up spool. 2. Programming PLUs (Price Look-Up)
The core of the SM-500’s functionality is the PLU system. You can program these directly on the device or via DIGI’s management software. digi sm-500 scale user manual
Entering Program Mode: Press the MODE key until the display indicates "S" (Programming) mode. Creating a New PLU: Enter the desired PLU number (e.g., 101) and press PLU.
Item Name: Use the alphanumeric keypad to type the product name (e.g., "Swiss Cheese"). Unit Price: Input the price per pound or kilogram.
Label Format: Assign a specific label template (usually Format 1 or 16). Save: Press ENTER or PLU to store the data. 3. Operating the Scale Once programmed, daily operation is straightforward:
Manual Weighing: Place the item on the scale, enter the PLU number, and press the PRINT key.
Tare Operations: For items in containers, place the empty container on the scale and press TARE. The scale will subtract this weight automatically from the final total.
Pre-Pack Mode: If you are labeling multiple identical items, toggle the "Pre-Pack" function to automatically print a label every time a stable weight is detected. 4. Maintenance and Troubleshooting
Regular maintenance ensures the longevity of the thermal print head and weighing sensors. Common Troubleshooting Codes Error Code OF Remove excess weight from the platter. UF Ensure the platter is seated correctly; re-zero the scale. Label End Out of Paper Replace the label roll and check the sensor alignment. Cleaning Tips
Print Head: Use a thermal cleaning pen or a lint-free cloth with 90% isopropyl alcohol to wipe the print head every time you change a label roll.
Platter: Use a damp cloth with mild detergent. Avoid spraying liquids directly into the internal components. 5. Advanced Networking
The DIGI SM-500 supports TCP/IP Ethernet and Wireless (802.11b/g) connections. This allows for: Centralized price updates across multiple scales. Remote diagnostics and reporting. Integration with back-office POS (Point of Sale) systems.
For detailed wiring diagrams or specific firmware update procedures, refer to the DIGI SM-500 Technical Service Manual, as these steps require administrator-level access. AI responses may include mistakes. Learn more
serves as a critical bridge between inventory management and point-of-sale efficiency. Unlike basic weighing machines, the
is a networked device capable of processing complex PLU (Price Look-Up) data, printing detailed nutritional labels, and integrating with back-office software to track sales in real-time. Key Operational Features
Touchscreen Interface: The scale features a user-friendly display that allows operators to quickly navigate through thousands of PLUs. This reduces training time for new staff and speeds up the weighing process during peak hours. Label Customisation:
One of its strongest selling points is the high-speed thermal printer. It supports various label formats, including "linerless" labels, which reduce waste and allow for flexible label lengths depending on the amount of product information required. Networking Capabilities: The
can be connected via Ethernet or Wireless LAN. This allows a central office to push price updates to all scales in a store simultaneously, ensuring pricing consistency across departments. Basic Setup and Maintenance
To ensure the scale remains accurate and functional, the DIGI SM-500 User Manual outlines several essential procedures: Digi SM-500 Scale User Manual Comprehensive Operation &
Calibration and Levelling: Before use, the scale must be placed on a flat, stable surface. Operators should check the integrated level bubble and adjust the feet until it is centered.
PLU Programming: Adding products involves entering a unique code, description, price, and expiration date. This data can be entered manually on the scale or synced via a PC.
Printer Cleaning: Because the thermal print head is sensitive, it requires regular cleaning with an alcohol-based pen to prevent streaks on labels and prolong the life of the hardware. Why Documentation Matters
Accessing a comprehensive manual is vital for troubleshooting common issues like "Label Jam" or "No Connection" errors. Technical resources for the
often include diagnostic steps for the thermal head and instruction on how to reset the networking IP, ensuring minimal downtime for the business.
