AC Current
Do not exceed the maximum current rating for AC current measurement. Exceeding the maximum current
rating can cause a fuse to blow.
This section describes how to configure AC 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 [ACI] on the front panel.
Step 3 (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.
When making measurements using the 10A terminals, the presence of a signal on the 3A ter-
minals can cause significant errors.
