SHYP FA/JA-C Series Automatic Internal Calibration Electronic Balance

Overview

The SHYP FA/JA-C Series Automatic Internal Calibration Electronic Balance is a precision laboratory balance engineered for high-reproducibility mass measurement in regulated and research-intensive environments. Built upon electromagnetic force compensation (EMFC) sensor architecture, it delivers stable, drift-resistant weighing performance without mechanical wear associated with traditional strain-gauge systems. The core innovation lies in its fully motorized internal calibration system—featuring dual-cam actuated weight deployment—which executes traceable, temperature-compensated calibration cycles at user-defined intervals or on startup. This eliminates manual intervention, reduces operator-induced error, and ensures continuous metrological integrity across shifts. Designed and manufactured in Shanghai, the series conforms to fundamental requirements of ISO 9001 quality management systems and supports compliance workflows aligned with USP , ASTM E898, and GLP documentation standards.

Key Features

• Electromagnetic force compensation (EMFC) transducer delivering high linearity, low hysteresis, and long-term stability
• Fully automatic internal calibration with motor-driven dual-cam mechanism—enabling repeatable, non-contact calibration without external weights
• Five-sided transparent glass draft shield with optimized airflow geometry for rapid stabilization and minimal convection interference
• Backlit large-format LCD display (128×64 pixels) with adjustable contrast and multi-language interface support (English, Chinese, Spanish)
• Integrated overload protection, real-time fault diagnostics, and four-point linear calibration routine for enhanced accuracy across full range
• RS232C serial interface compliant with standard ASCII output protocols—enabling direct integration with PCs, thermal printers, and LIMS platforms
• Below-balance hook for density determination and suspended weighing applications
• Programmable auto-zero tracking, full-range tare, piece counting, and unit conversion (g, mg, ct, oz t, lb, etc.)

Sample Compatibility & Compliance

The FA/JA-C Series accommodates standard laboratory samples up to 300 g (JA3003C model), including powders, granules, liquids in containers, and small solid components. Its φ90 mm stainless-steel weighing pan and 240 mm vertical working clearance allow compatibility with common volumetric flasks, crucibles, and sample boats. All models meet essential electromagnetic compatibility (EMC) requirements per IEC 61326-1 and are constructed with flame-retardant ABS housing rated UL94 V-0. While not certified to OIML R76 or NIST Class I/II, the balances are suitable for non-legal-for-trade applications—including QC release testing, formulation R&D, educational labs, and preparatory analytical workflows—where internal calibration traceability and documented calibration history satisfy institutional SOPs.

Software & Data Management

Data output follows standard balance ASCII format (e.g., “S 123.4567 g” + CR/LF), supporting seamless ingestion into Excel, LabWare LIMS, Waters Empower, and Thermo Fisher SampleManager via serial-to-USB adapters. The built-in RS232C port supports baud rates from 1200 to 9600 bps with configurable parity and stop bits. Though no proprietary software is bundled, SHYP provides a basic terminal emulator configuration guide and ASCII command set documentation (including commands for tare, print, zero, and calibration trigger). For regulated environments, users may implement third-party data capture tools with 21 CFR Part 11-compliant audit trails, electronic signatures, and calibration event logging—leveraging the balance’s deterministic calibration timestamping and status reporting.

Applications

• Pharmaceutical formulation development and excipient dosing verification
• Chemical reagent preparation and stoichiometric mass assignment
• Materials science lab work involving catalyst loading, polymer blending, and nanomaterial dispersion
• Food and beverage QC for ingredient batching and nutritional labeling compliance
• University teaching laboratories requiring robust, low-maintenance instrumentation for introductory analytical chemistry courses
• Density determination of solids and liquids using the integrated below-balance hook and auxiliary sinker accessories

FAQ

Does this balance support external calibration with certified weights?
Yes—while designed for automatic internal calibration, all FA/JA-C models include a manual calibration mode accepting external Class E2 or better reference weights.
Is temperature compensation active during internal calibration?
Yes—the internal calibration algorithm incorporates real-time ambient temperature sensing and applies correction coefficients based on factory-characterized thermal drift profiles.
Can the RS232 output be configured for continuous streaming?
No—output is triggered only upon stabilization (via “S” command) or on demand (e.g., “P” for print); continuous polling requires host-side timing control.
What is the warm-up time required for optimal accuracy?
Minimum 30 minutes at stable ambient temperature (20 ±2 °C); full specification accuracy is guaranteed after 60 minutes of continuous operation.
Are calibration records stored internally?
No—the balance does not retain historical calibration logs; timestamps and pass/fail status are transmitted only in real time via RS232 during calibration execution.
