2. Make the connection as shown in Figure B-2 in order to measure DC voltage. You can

control the U2741A via the Agilent Measurement Manager (AMM) software for U2741A or

via SCPI commands sent through the USB interface from your own application programs.

3. If you are using the AMM, select the DCV function located at the top-left corner. Set the

desired range under Range section. A suitable range should be selected to give the best

measurement resolution. The reading is displayed and updated continuously.

4. If you are using SCPI commands, enter MEASure[:VOLTage]:DC? in order to make a DC

voltage measurement.

Measuring DC Current

1. The DC current measurement function of the U2741A has the following features:



three ranges to select: 10 mA, 100 mA, 1 A, and 2 A; or auto range



input impedance is 10 MΩ for all ranges (typical)



input protection fuse is 2 A, voltage rating 250 V on all ranges

2. Make the connection as shown in Figure in order to measure DC current. You can control

the U2741A via the Agilent Measurement Manager (AMM) software for U2741A or via SCPI

commands sent through the USB interface from your own application programs.

3. If you are using the AMM, select the DCI function located at the top-left corner. Set the

desired range under the Range section. A suitable range should be selected to give the best

measurement resolution. The reading is displayed and updated continuously.

4. If you are using SCPI commands, enter MEASure:CURRent[:DC]? in order to make a DC

current measurement.
