Impedance test system BATT470m

The BATT470m electrochemical impedance analysis interface (EIS) provides an easy to use battery impedance test platform for the electrochemical industry. Utilizing the highly accurate PSM3750 frequency response analyzer from N4L, the BATT470 provides impedance measurement of batteries/cells up to 200V DC. With a frequency range of 100mHz to 1MHz, the BATT470m covers a wide range of applications. Our software package PSMComm2, featuring “EIS” mode, displays the in-phase and quadrature impedance of the cell in Nyquist form as well as overall impedance (Z) in bode form. The BATT470m features DC blocking circuitry, protecting the PSM3750 generator from the high DC voltages produced by the device under test. The ESF10m (supplied with the BATT470m) houses a 10mHz high pass filter circuit, AC coupling the inputs of the PSM3750. AC coupling allows the PSM3750 to utilise a low range, (ranging upon the AC component only) reducing error and improving low level voltage/current measurement.
