A&D FG Series Precision Platform Scales

Overview

The A&D FG Series Precision Platform Scales are industrial-grade weighing instruments engineered for high-throughput laboratory, quality control, and production floor environments where speed, repeatability, and regulatory compliance are critical. Built in Japan and designed to meet international metrological standards—including JIS B 7301 and OIML R76 Class III—the FG series employs electromagnetic force compensation (EMFC) load cell technology to deliver stable, drift-free measurements across diverse ambient conditions. With stabilization times of ≤1 second and selectable readability modes (e.g., 2 g / 5 g / 10 g for the FG-30KAM), these scales support dynamic weighing workflows without compromising accuracy. The modular architecture accommodates both light-duty (30 kg) and heavy-duty (150 kg) applications while maintaining consistent linearity and temperature stability—key requirements for GLP/GMP-aligned processes in pharmaceutical, food, and component manufacturing settings.

Key Features

• Rapid Stabilization: Achieves stable readings in ≤1 second—optimized for high-volume batch verification and inline inspection tasks.
• Triple-Resolution Mode: User-selectable readability options (e.g., 1/3000, 1/6000, or 1/12000 of full scale) enable application-specific precision tuning without hardware modification.
• Intuitive LCD Interface: Backlit large-character display shows real-time weight, status flags (Stable/Net/Tare/Zero), and comparator results (HI/OK/LO) with unambiguous iconography.
• Advanced Counting Function: Supports sample counts of 5, 10, 20, 50, or 100 units; automatically calculates average piece weight and total count with statistical deviation reporting.
• Comparator Output Capability: Optional FG-24 interface provides discrete HI/OK/LO relay outputs compatible with PLCs, alarm lights, or automated sorting systems per ASTM E1772 and ISO 14253-1 protocols.
• Traceable Calibration: External calibration using certified weights ensures ongoing metrological integrity; built-in calibration log supports FDA 21 CFR Part 11 audit trails when paired with compliant software.
• Dual Power Flexibility: Operates via universal AC adapter or four C-cell alkaline batteries (R14P/LR14) with low-battery indicator and auto-shutdown after ~5 minutes at zero-load—reducing energy waste and extending service intervals.
• Ergonomic Design: Adjustable-height display pole and tiltable head improve operator posture and viewing angle; stainless steel pans (300 × 380 mm M-type or 390 × 530 mm L-type) resist corrosion and simplify cleaning under ISO 22000 hygiene requirements.

Sample Compatibility & Compliance

The FG Series accommodates irregularly shaped, bulky, or vibration-sensitive loads—including packaged goods, raw materials, and assembled components—without requiring repositioning or damping accessories. Its robust mechanical design minimizes sensitivity to floor vibrations and air currents common in non-isolated production areas. All models conform to OIML R76 Class III accuracy class for non-automatic weighing instruments, making them suitable for trade-related applications subject to national metrology authority oversight. When used with documented calibration records and validated procedures, the scales support compliance with ISO/IEC 17025 testing laboratories, USP balance performance verification, and EU Annex 11 data integrity expectations. Gravity acceleration correction allows deployment across global sites without recalibration due to geographic latitude or elevation differences.

Software & Data Management

Equipped with optional RS-232C serial communication (via FG-23 or FG-24 modules), the FG Series integrates seamlessly into enterprise data ecosystems. ASCII-compatible output enables direct logging into LIMS, MES, or custom SCADA platforms. The comparator output signal (FG-24) is TTL-level compatible and configurable for fail-safe logic in automated packaging lines. For regulated environments, third-party software solutions—validated per GAMP 5 guidelines—can capture timestamps, operator IDs, weight values, and pass/fail decisions with full audit trail functionality aligned with FDA 21 CFR Part 11 electronic record requirements. Internal memory retains calibration history and system diagnostics accessible via service mode.

Applications

• Pharmaceutical tablet and capsule counting in QC release testing
• Food ingredient batching and portion control in HACCP-compliant facilities
• Automotive component verification on final assembly lines
• Logistics parcel dimensioning and weight validation prior to shipping
• Recycling center material sorting by mass thresholds
• Education and vocational training labs emphasizing metrological best practices

FAQ

What accuracy class does the FG Series comply with?
The FG Series meets OIML R76 Class III requirements for non-automatic weighing instruments, supporting legal-for-trade use in many jurisdictions when installed and maintained per manufacturer specifications.
Can the FG scale be calibrated internally without external weights?
No—calibration requires certified external test weights; internal calibration is not supported. This ensures traceability to national standards and satisfies ISO/IEC 17025 clause 6.5.2.
Is the RS-232C interface optically isolated?
The FG-23 and FG-24 modules do not include optical isolation; users deploying in electrically noisy industrial environments should install external isolation adapters to prevent ground loop interference.
Does the FG Series support Ethernet or USB connectivity?
No—only RS-232C serial communication is natively supported. Network integration requires a serial-to-Ethernet converter configured as a virtual COM port.
How is gravity acceleration correction applied during setup?
Users enter local gravitational acceleration value (m/s²) or select geographic region from an onboard menu; the scale applies real-time compensation to displayed mass values without affecting calibration constants.
