Access point for PLU entry, label layout adjustments, and system spec data modification. 2. Advanced PLU Programming Workflow

Press the power button; the unit will self-test and display the weight readout.

High-speed thermal printing (up to 150mm/s) with an 80mm wide label capability.

Each visual element on a label is treated as an independent field defined by an X (horizontal) and Y (vertical) coordinate grid.

Understanding the physical layout and technical capabilities of the DIGI SM-500 ensures long-term operational success and prevents common hardware mishaps. Structural Components

Faint text or white vertical lines through barcodes indicate a dirty print head. Power down the scale entirely. Open the printer side compartment cover.

Calibration is a critical step to ensure accurate weighings. Here's how to calibrate your Digi SM500 scale:

Dual-sided, high-contrast matrix LCD or dot-matrix display indicating Weight, Tare, Unit Price, and Total Price.

Environmental vibration or mechanical interference under the platter.
