Description

ATOMFAIR® BIT-5289 BATTERY INTERNAL RESISTANCE TESTER

RESEARCH GRADE MATERIAL

Product Overview
The ATOMFAIR® Atomfair-BIT-5289 Resistance Tester is an elite, high-resolution benchtop instrument meticulously optimized for the non-destructive profiling and continuous electrochemical degradation diagnosis of clean energy architectures. Functioning as a high-precision 1kHz Battery Ohm Meter, this platform sweeps past traditional measurement drift by applying a stabilized AC injection frequency to isolate true vector impedance parameters. The advanced processing matrix implements absolute simultaneous measurement precision, locking both open-circuit voltage and internal resistance tracks within a singular high-speed data sweep. Highly compatible with leading lead-acid, pouch-cell lithium, and advanced polymer configurations, it delivers uncompromised grading repeatability and automated data acquisition for world-class laboratories and production quality control lines.

Key Features & Advantages
  • Transient Dual Parameter Sampling: Completes synchronized internal resistance and open circuit voltage (OCV) detection algorithms within 10 ms to optimize high-speed cell grading.
  • Comprehensive Multi-Range Zeroing: Outfitted with an automated short-circuit zero calibration protocol spanning all 7 hardware ranges, removing stray lead resistance from micro-ohm readouts.
  • Industrial Opto-Isolated Handler: Features a dedicated PLC Handler interface matching 30 comparator groups for rapid, automated physical sorting chains on production conveyor links.
  • High-Volume Quality Management Logging: Retains a non-volatile 30,000 record internal capacity, allowing seamless CSV data dumps via the front panel USB Host block without tracking loss.

APPLICATION SCOPE: Highly recommended for screening cell match uniformity, diagnosing lithium-ion pouch degradation, classifying lead-acid storage cells, and verifying high-accuracy technical resistances.
PACKAGING: Securely shipped within an export-grade cushioned transport enclosure, complete with 4-wire Kelvin test probes and a detailed calibration validation report to verify absolute resolution tolerances.
IMPORTANT NOTICE: Never connect the measurement leads across active voltage potentials exceeding the 60 V DC chassis limitation threshold. Perform full short zero calibrations whenever modifying test probe configurations or changing localized work environments.

This high-precision internal resistance tester requires AC power 110-220V and must be operated with proper grounding. Short zero calibration across full ranges is necessary before measurement to ensure accuracy.

  • Electrical Safety: Connect the instrument to a grounded AC outlet and avoid contact with test leads while powered.
  • Calibration Requirement: Perform short zero calibration across all seven resistance ranges before each measurement session.
  • Environmental Constraint: Operate in a clean, dry environment to prevent moisture ingress and electrical hazards.
  • Overload Protection: Do not exceed the maximum voltage input of 60 V or apply external voltage to the test terminals.
  • Data Management: Export stored data via USB disk to free internal memory for continued testing.

Initialize the tester for safe operation by connecting power and performing calibration. Measure internal resistance and voltage by selecting range and test speed.

Required Equipment: Test leads, AC power cord, USB storage device

  1. Prepare Power Connection
    Connect the AC power cord to a grounded outlet and verify the display illuminates.
  2. Perform Short Zero Calibration
    Short the test leads together and press the calibration button to zero the resistance reading across all ranges.
  3. Select Measurement Range and Speed
    Set the range to auto or manual and choose the desired test speed from 3 to 100 measurements per second.
  4. Connect Battery Under Test
    Attach the test leads to the battery terminals ensuring correct polarity and secure contact.
  5. Record Measurement Data
    Trigger a measurement and observe the displayed resistance and voltage, then store or export the data as required.

How does the 1 kHz AC test signal affect the accuracy of internal resistance measurements on lithium polymer batteries compared to DC methods?

The 1 kHz AC test signal is the industry standard for measuring AC internal resistance and provides accurate, non-destructive results for all battery types including lithium polymer. The Atomfair-BIT-5289's test signal has an open circuit voltage less than 5 V and test current less than 100 mA, ensuring safety and repeatability without DC-induced polarization errors. Resistance accuracy is ±0.5% rdg. ±5 dgt., and voltage accuracy is ±0.01% rdg. ±3 dgt., as specified in the technical data.

Can the Atomfair-BIT-5289 be integrated into an automated test system with a PLC for production line sorting?

Yes. The Atomfair-BIT-5289 features a Handler (PLC interface) and RS-232C for direct integration with automated systems. It supports up to 30 comparator groups with 2-4 step sorting, external trigger mode, and data export via USB for seamless production line quality control. The instrument can measure simultaneously resistance and voltage within 10 ms, enabling high-speed inline testing at up to 100 measurements per second.

What calibration procedure is required before using the Atomfair-BIT-5289 for high-precision measurements?

The Atomfair-BIT-5289 requires a short zero calibration across all ranges to eliminate test lead and contact resistance. This is performed by shorting the test leads and using the built-in calibration function. The instrument operates on universal AC power (110–220 V ±10%, 50/60 Hz) and consumes only 15 W, making it suitable for lab bench and portable use. No other special infrastructure is needed.

The Atomfair-BIT-5289 delivers 0.01 mOhm resolution and 10 ms simultaneous resistance-voltage measurement, enabling high-accuracy, high-throughput battery screening for all major chemistries, but demands AC mains power and periodic zero calibration across all ranges.

Positive

  • High precision and resolution: Resistance accuracy of ±0.5% rdg. ±5 dgt. and 0.01 mOhm resolution at the 300 mOhm range enable reliable detection of subtle internal resistance changes in all battery types.
  • Fast simultaneous measurement: Simultaneous resistance and voltage measurement within 10 ms supports high-speed sorting and quality control with selectable rates up to 100 measurements per second.

Trade-offs

  • AC power dependency: Operates only on AC 110–220 V mains supply (15 W), preventing field or portable use without an external inverter or dedicated lab power.
  • Calibration overhead: Requires short zero calibration across all seven measurement ranges, adding setup time and necessitating periodic recalibration to maintain specified accuracy.
