DC Current
This section describes how to configure the selected channel for DC current measurements from the front
panel.
1.
Connect DC current source to the module's screw terminals.
2. Press [Channel] > Measure, and select DCI from the selection menu.
3. Press Range and use the knob or the front panel arrow keys to specify the measurement 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 present range.
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 100 PLC provides the best
noise rejection and resolution, but the slowest measurements..
NPLC - Sets the integration time as 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.
Time - Directly sets the integration time in seconds.
