Features

Fast stabilization in about 0.8 seconds for efficient weighing*1 Flexible power options: AC adapter, USB Type‑C power, or AA batteries High-contrast reverse backlit LCD with large 18 mm characters Stainless steel (SUS 304) weighing pan that is durable and easy to clean Impact shock detection (ISD) warning of shocks to maintain accuracy and protect the sensor (patented) Counting mode with ACAI for more accurate piece counting Percent mode for quick comparison against a reference value Comparator function showing HI, OK, or LO for fast checkweighing Memory for up to 20 comparator limit sets for easy reuse and quick changeover Auto-tare and negative comparison for efficient “take-away” weighing Sonic communication for cable‑free data transfer to mobile devices (patented) Adjustable response characteristics to match different environments Display hold function for easy reading under unstable conditions Multiple units of measure*2: g, oz, lb, ozt, ct, mom, dwt, and gr Auto power ON/OFF to save time and reduce energy use GLP/GMP/GCP/ISO compliant output for regulated environments ZPL output for direct printing in preset formats, including one with a QR code, on Zebra printers Password lock and key restriction to prevent unauthorized changes Spirit level with LED reminder and four leveling feet for proper balance setup Security slot compatible with anti‑theft locks *1 Typical for 100 g and 1,000 g on 0.01 g and 0.1/1 g models respectively, at the fastest response setting. *2 One additional unit from either tael (Singapore, HK jewelry or Taiwan), tola or Newton can be added upon request.
