ParameterDescription
MeasurementsDisplays the voltage and current measurements on a per channel basis.
ConfigurationContains the following options:
  • Device—Contains the resource name of the device.
  • Enable/Disable all outputs—Specifies whether all output channels are enabled or disabled.
  • Channel Configuration
    • Channels—Select channel by highlighting. The channel configuration for selected channel is displayed.
    • Output Function—Configures the function to generate on the specified channel(s).
    • Output Enabled—Specifies whether the output is enabled or disabled.
    • Voltage Level (V)—Specifies the voltage level, in volts, the device attempts to generate on the specified channel(s). Valid values for the voltage level are defined by the voltage level range.
    • Current Limit (A)—Specifies the current limit, in amps, for the output not to exceed when generating the desired voltage on the specified channel(s). Valid values for current limit are defined by the current limit range.
    • Voltage Level Range (V)—Specifies the voltage level range, in volts, for the specified channel(s). The range defines the valid values to which the voltage level can be set.
    • Current Limit Range (A)—Specifies the current limit range, in amps, for the specified channel(s). The range defines the valid values to which the current limit can be set.
    • Voltage Level Autorange—Specifies whether or not NI-DCPower automatically selects the voltage level range based on the desired voltage level for the specified channel(s).
    • Current Limit Autorange—Specifies whether or not NI-DCPower automatically selects the current limit range based on the desired current limit for the specified channel(s).
    • Current Level (A)—Specifies the current level, in amps, the device attempts to generate on the specified channel(s). Valid values for the current level are defined by the current level range.
    • Voltage Limit (V)—Specifies the voltage limit, in volts, for the output not to exceed when generating the desired current level on the specified channels. Valid values for the voltage limit are defined by the voltage limit range.
    • Current Level Range (A)—Specifies the current level range, in amps, for the specified channel(s). The range defines the valid values to which the current level can be set.
    • Voltage Limit Range (V)—Specifies the voltage limit range for the specified channel(s). The range defines the valid values to which the voltage limit can be set.
    • Current Level Autorange—Specifies whether or not NI-DCPower automatically selects the current level range based on the desired current level for the specified channel(s).
    • Voltage Limit Autorange—Specifies whether or not NI-DCPower automatically selects the voltage limit range based on the desired voltage limit for the specified channel(s).

ParameterDescription
Close (T)Specifies whether the session to the device remains open after the VI finishes execution. Set Close (T) to TRUE to close all references and reinitialize the device for each iteration. Set Close (T) to FALSE for all iterations except the last iteration for loop optimization. The default is TRUE.
error inDescribes error conditions that occur before this VI runs.

Block Diagram Outputs

ParameterDescription
Measured VoltageReturns the voltage values measured on all output channels.
Measured CurrentReturns the current values measured on all output channels.
error outContains error information. If error in indicates that an error occurred before this Express VI ran, error out contains the same error information. Otherwise, error out describes the error status that this Express VI produces.
