Queries the maximum voltage level on a channel if the channel is set to the specified currentLimit.

Syntax

ViStatus _VI_FUNC niDCPower_QueryMaxVoltageLevel(ViSession vi, ViConstString channelName, ViReal64 currentLimit, ViReal64 *maxVoltageLevel)

Parameters

NameDirectionTypeDescription
vi[in]ViSession

Identifies a particular instrument session. vi is obtained from the niDCPower_InitializeWithIndependentChannels function.

channelName[in]ViConstString

Specifies the channel to query. The maximum voltage level may only be queried for one channel at a time.

Specify the channel using the form PXI1Slot3/0, where PXI1Slot3 is the instrument resource name and 0 is the channel.

currentLimit[in]ViReal64

Specifies the current limit to use when calculating the maxVoltageLevel.

maxVoltageLevel[out]ViReal64 *

Returns the maximum voltage level that can be set on a channel with the specified currentLimit.

Returns
