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.

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)
