AT5320 20-Channel Battery Internal Resistance Tester

The AT5320 is a compact bench-top instrument featuring full-automatic real-time measurement, controlled by a high-performance 32-bit ARM microprocessor. It can scan and test the internal resistance and voltage of up to 20 battery channels simultaneously. The instrument measures resistance from 0.001mΩ to 3kΩ and DC voltage from 0.0001V to 60.000V, with 30,000 display counts for resistance and 60,000 display counts for voltage.

The AT5320 supports mixed testing of resistance across 20 different batteries, with independent comparator settings for each channel. The comparator results from all 20 channels can be output in sequence via the Handler interface. Standard interfaces include RS-232, RS-485, USB communication, and Handler interface.
