CPC 100 V1.414 - 40Pressing the S E T T I N G S menu key opens the Settings page. The Settingspage allows setting the test cards individually. As a rule, do not use the Settingspage but the Device Setup tab in the Options view (see ”Device Setup” onpage 2-33) to set the test cards. For more information, see ”Settings Page” onpage 2-28.MeasurementsSelecting the check box "Manual input" lets you enter the value for Vsecmanually, for example, when Vsec was measured with an external volt meterrather than at input V2AC.Iprim:(lower field)actual output current at the output that is injected into theRogowski coil’s current-carrying conductorVsec: secondary voltage measured at V2ACI’sec: calculated secondary current. I’sec =with k = Iprim nom / (Vsec nom x 1s).Note that the current I’sec does not really exist in the system. Itis a calculated current only.° phase angle of calculated secondary current with reference tothe primary currentRatio: Iprim / I’sec, here 240.0:239.97 11. The value 239.97 is calculated as follows:(I’sec / Iprim) x Iprim nom; here: (239.84A / 239.87A) x 240 A = 239.97A% and deviation of current ratio in %. Formula:((I’sec - Iprim) / Iprim) x 100%((239.84A - 239.87A) / 239.87A) x 100% = -0.012%Polarity: displays the status of the polarityOK = phaseI’sec - phaseIprim = -45° < 0° < 45°NOT OK = all other casesk V tdsec∫
