CPC 100 V1.417 - 6MeasurementsSelecting the check box "Manual input" lets you enter the value for VDCmanually, for example, when VDC was measured with an external volt meterrather than at input VDC.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 current increases from 0A to Itest in a ramp characteristic within1 second. Then Itest is kept for a period of 1 second, and the measurementsare taken. Next, the ramp decreases again within 1 second.– 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 current Itest manually with the handwheel.– Press the I/O (test start/stop) push-button to start the test. The focus is setonto the "I 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.– To save the measurement press K E E P R E S U L T S (pressing the I/O push-button has the same effect). The last measured values are "frozen", the testcan now be assessed.IDC: actual test current that is injected into the test objectVDC: measured voltage drop at the test objectR: calculated resistance of test object, R = VDC / IDCNote: "Manual Input" cannot be selected at the range VDC (2 wire).Note: 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.
