Dears, I am using the CR8348-2000 Current Sensor and and i need the Sensitivity Value [V/A]parameter. This parameter is part of a formula that is shown at table 3, on page 19 in attached. Thank you. Marcus p.s. can i calculate it by the formula in attached "formula.jpg"?

Dear Sir, This value V/A is determined by the burden resistor placed across secondary of the CT. CR8300 series CTs are shipped without installed burden. Please note the effective ratios given in our spec sheet to determine your V/A value by dividing the input current through the ring by the effective ratio given in our spec sheets. This multiplied by the user defined burden connected will give you the V/A ratio. Be sure to choose the burden resistor low enough to allow enough overhead for proper linearity. Figure 9 part b in your document is the correct configuration.
