3.Measurement

1. 1Choose variable powerat the left menu of Touch LCD panel.

   

2. 2Choose 3 CH DC tab and click arrowat DC Voltage V1 to set up 10V, and click arrow at DC Voltage V2 to set up 8V.

   If you double-click DC Voltage V1 and click one, zero and ok using Quick Number Keypad, it can be input directly.

   If you click on, the output of DC 10V is input to V1, and the output of DC 8V to V2.

   

3. 3Compose the connection as Measuring Instrument>Ammeter Connection>I-1 Current Measurement> and click dmmat the left menu, then Digital Multi Meter window appears. If you click dci, the current value and current direction of I-1 is measured. Record it in Fig. I-1 of table 1-3.

   

4. 4Compose the connection as Measuring Instrument>Ammeter Connection>I-2 Current Measurement>and then the current value and current direction is measured in Digital Multi Meter window. Record it in Fig. I-2 of table 1-3.
5. 5Compose the connection as Measuring Instrument>Ammeter Connection>I-3 Current Measurement>and then the current value and current direction is measured in Digital Multi Meter window. Record it in Fig. I-3 of table 1-3.

4.Calculation

1. Calculate the current value according to the formula and record it in the table.
