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: Press the Aperture NPLC softkey and 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 rejection and
resolution, but the slowest measurements.

Step 4

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.

Step 5: Press Range to select a range for the measurement. You can also use the [+], [-], and
[Range] keys on the front panel to select the range. (Auto (autorange) automatically selects the
range for the measurement based on the input. Autoranging is convenient, but it results in slower
measurements than using a manual range. Autoranging goes up a range at 120% of the present
range and down a range below 10% of the current range. Press More to switch between the two
pages of settings.

Step 6: Auto Zero: Autozero provides the most accurate measurements, but requires additional
time to perform the zero measurement. With autozero enabled (On), the DMM internally measures
the offset following each measurement. It then subtracts that measurement from the preceding
reading. This prevents offset voltages present on the DMM’s input circuitry from affecting
measurement accuracy. With autozero disabled (Off), the DMM measures the offset once and
subtracts the offset from all subsequent measurements. The DMM takes a new offset measurement
each time you change the function, range, or integration time. ( There is no autozero setting for 4-wire
measurements.)

Step 2: Press [ACI] on the front panel.


Step 3: 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.
CAUTION When making measurements using the 10A terminals, the presence of a signal
on the 3A terminals can cause significant errors.
