CPC 100 V1.415 - 10MeasurementsSelecting the check box "Manual input" lets you enter the value for Isecmanually, for example, when Isec was measured with a current clamp ratherthan at input IAC.Automatic Test vs. Manual Test1. Option "Manual input" clearAutomatic test– Press the I/O (test start/stop) push-button to start the test.The test voltage increases in a ramp characteristic from 0V to Vtest within1 second. Then Vtest is kept and injected for a period of 2.4 seconds, themeasurements are taken. Next, the ramp decreases again within0.3 seconds.– The automatic test stops by itself, it can now be assessed.– To repeat the test, first press B A C K T O T O P , if applicable, and then C L E A RR E S U L T S .Manual testClearing "Auto" lets you set the test voltage Vtest manually with the handwheel.– Press the I/O (test start/stop) push-button to start the test. The focus is setonto the "V test:" entry field.– Set the value of your choice either by turning the handwheel and/or byentering it with the numerical keys.– Now the measurements are taken and displayed.Vsec: actual voltage at the burden, measured at input V1ACIsec: actual current through burden, measured via input IACBurden: burden in VA: Vsec nom × (Isec act × Vsec nom/Vsec act)cosϕ cosinus of phase angle ϕNote: A value set with the numerical keys needs to be fully entered andacknowledged by pressing either E N T E R or the handwheel beforeit is applied to the output. If needed, it can then be adjusted usingthe handwheel.Values set by turning the handwheel are applied instantaneously.
