DC Voltage
This section describes how to configure the selected channel for DC voltage measurements from the front panel.
1. Connect the voltage source to the module's screw terminals.
2. Press [Channel] > Measure, and select DCV from the selection menu.
3. Press Range and use the knob or the front panel arrow keys to specify the measurement range. Auto (autor-
ange) 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 present range.
Autorange is not supported on the DMM Digitize data acquisition mode.
4. Press Integrate Settings softkey to select whether the measurement integration time will be specified in terms of
Number of Power Line Cycles (NPLC) or directly in seconds (Time). Only 1, 2, 10, 20, 100, and 200 PLC provide
normal mode (line frequency noise) rejection. Selecting 200 PLC provides the best noise rejection and res-
olution, but the slowest measurements.

Description
Sets the integration time as 0.001, 0.002, 0.006, 0.02, 0.06, 0.2, 1, 2, 10, 20, 100, and 200 Power Line
Cycles (PLC). Only 1 PLC and longer times provide normal mode (line frequency noise) rejection.
Selecting 100 or 200 PLC provides the best noise rejection and resolution.
Directly sets the integration time in seconds.
