DC Current
This section describes how to configure DC current measurements from the front panel.
Step 1: Configure the test leads as shown.
On the 34461A/65A/70A, you can also configure the measurement using the 10 A terminal, which is
recommended when measuring current above 1 A:
Step 2: Press [DCI] on the front panel.
Step 3: For the 34465A/70A, the Aperture NPLC softkey is selected by default. Use the up/down arrow
keys to specify integration time in power-line cycles (PLCs) to use for the measurement . 1, 10, and 100
PLC provide normal mode (line frequency noise) rejection. Selecting 100 PLC provides the best noise rejec-
tion and resolution, but the slowest measurements:
Step 4 (34461A/65A/70A only): The 3A terminals are selected by default. The Terminals softkey toggles
between the 3 A terminals and the 10 A input terminals. When you change this to 10 A, the measurement
range automatically becomes 10 A.
