Measuring AC+DC current
The U3606A Multimeter|DC Power Supply includes a true- rms multimeter 
that returns an accurate rms reading not only for sine waves, but also 
other AC signals such as square, triangle, and staircase waveforms without 
any DC offset. However, you may choose to return the measured AC signal 
with DC offset by using the AC+DC function.
The AC+DC current measurement measures AC current with DC offset.
1 Press   again (until the AC+DC annunciator is shown on the display) 
to make AC+DC current measurements.
2 Connect the red and black test leads to input terminals I (red) and 
LO (black) respectively as shown in Figure 2- 2.
3 Probe the test points and read the display.
