New GW Instek GBM-3000 battery testers

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

The series features 3.5" TFT LCD, 4-wire measurement method, high-resolution (6-digit voltage / 5-digit resistance) measurement display capability, and independent GO/NOGO determination of voltage and resistance, various communications interfaces, etc. to meet various types of battery measurements, ranging from single cell, battery cell, to the end product (battery). For voltage measurement, the accuracy is as high as ± (0.01% reading + 3 digits), and measurement resolution is up to 10μV (at 8V). For resistance measurement, the accuracy reaches ± (0.5% reading + 5 digits) and the resolution achieves 0.1μΩ (at 3mΩ) that is especially suitable for the sorting of single cell measurements, which is to achieve a better output balance for the follow-up series and parallel connections.

Other than the excellent measurement capabilities, the GBM-3000 series also provides a number of functions to ensure effectiveness and convenience. For the effectiveness, the test lead (probe) contact status detection function is to effectively prompt users whether test lead (probe) and DUT are in good contact to ensure the validity of the measured value. In terms of convenience, the GBM-3000 series provides two data storage methods (up to 10,000 lots of measurement values). "General storage" only stores the measured voltage and resistance values; "statistical storage" has the related parameters (Cp/Ckp/Mean/MAX/MIN...) for the statistical analysis.
