Model 3561 Battery HiTester is a low-resistance meter employing the fourterminal AC method to measure the internal resistance (IR) of small secondary batteries while measuring battery voltage at the same time. Compared to Model 3560, performance capabilities have been greatly enhanced by increasing measurement speed tenfold to 10 ms (measuring resistance and voltage simultaneously), and increasing voltage measurement accuracy nearly fivefold to 0.01% rdg. The high-resolution 0.01 m-Ohm (in the 300 m-Ohm range) and 0.1 mV capabilities are ideally suited to production line battery testing. The many built-in features include comparator and statistical calculation functions and a variety of interfaces, making Model 3561 suitable for a wide range of applications including quality and process control such as in high-speed automated assembly lines.

The built-in RS-232C interface enables data transfer at up to 38,400bps, or about 10ms per measurement. Connect to the 9670 Printer for instantaneous printouts of measurement results and statistical calculations. Choose Model 3561-01 for additional GP-IB interfacing capabilities.

Triggering, loading of measurement setting configurations and zero-adjustment can be externally controlled. The 3561 provides outputs for comparator results, end-of-measurement and measurement error notifications.
