VTI Instruments EX1629 - Vtex1629_Set_Unstrained_Voltage

VTI Instruments Corp.
294 EX1629 Command Set
vtex1629_set_unstrained_voltage
FUNCTION PROTOTYPE
ViStatus vtex1629_set_unstrained_voltage (ViSession vi, ViInt32 _VI_FAR channels[], ViInt32
numberOfChannels, ViReal64 unstrainedVoltage);
FUNCTION PARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
channels = an input integer array containing a list of channel numbers for which the unstrained voltage will be set.
Valid input values: 0 to 47.
numberOfChannels = the size of the channels list. Valid input values: 1 to 48.
unstrainedVoltage = a real input value that indicates the unstrained voltage to set for the given list of channels.
DATA ITEM RESET VALUE
unstrainedVoltage = 0.000000
DESCRIPTION
This function sets the unstrained voltage for a list of channels. This is one parameter in the EU calculations.
NOTE The conventional method of providing an unstrained voltage value to the EU conversion is to
conduct an unstrained voltage measurement using the vtex1629_measure_unstrained_voltage
function. This function provides a manual method that is normally only used for system diagnostic
purposes.
EXAMPLE
ViSession instrumentHandle;
ViStatus status;
ViInt32 channels[] = {0};
…
status = vtex1629_set_unstrained_voltage(instrumentHandle, channels, 1, 0.01);
