GW Instek GBM-3000 series desktop battery tester

GW Instek has launched the GBM-3000 series desktop battery tester, which uses AC 1 kHz as the test signal and measures a battery’s voltage and internal resistance to 300 V (GBM-3300) and 80 V (GBM-3080).

The series features 3.5″ TFT LCD, a 4-wire measurement method, a high-resolution (6-digit voltage/5-digit resistance) measurement display capability, independent GO/NOGO determination of voltage and resistance, and various communications interfaces to meet various types of battery measurements, ranging from single cell to battery cell to the end product (battery), helping users achieve correct measurements at all stages of production.

The series provides several features for various types of batteries in measuring open circuit voltage and resistance. For voltage measurement, the accuracy is as high as ±(0.01% reading + 3 digits) and measurement resolution is up to 10 μV (at 8 V). For resistance measurement, the accuracy reaches ±(0.5% reading + 5 digits) and the resolution achieves 0.1 μΩ (at 3 mΩ), which is particularly suitable for the sorting of single cell measurements to achieve a better output balance for the follow-up series and parallel connections.

In order to help users quickly and clearly interpret the measurement results, the series features HI/LO determination based on voltage and resistance respectively and can be switched to the simple (big numerical display) mode to meet the requirements of test accuracy. Results are made clear and easy to read, with elevated inspection efficiency and capabilities.
