3. Voltmeter Superimposed current Fig 1 1 KFM2005 configuration The KFM2005 incorporates a high performance constant current AC circuit that enables a given AC current Superimposed current to be supplied to the fuel cell By connecting sensing wires to the output terminals of the fuel cell the KFM2005 samples the AC voltage to calculate the impedance Therefore highly accurate measurements can be made even when resistance or inductance components in the wires or contact resistance exist The power that the fuel cell generates is absorbed by allowing DC current to flow through the load device from the LOAD terminal A superimposed current is supplied by the constant current AC circuit through the LOAD terminal to the fuel cell The superimposed current does not flow through the load device in the process The impedance is calculated using the AC voltage that is measured by the SENSING terminal and the superimposed current General Description 15 16 Rack Mounting Option The following options are available for the KFM2005 For details on the options contact your Kikusui agent or distributor Item Model Notes Rack mount KRB2 TOS Inch rack EIA standard bracket KRB100 TOS Milli rack JIS standard KFM2005 Installation and Preparation This chapter describes the procedures of unpacking and preparation of the KFM2005 before use Checking the Package Contents When you receive the product chec
