EX1629 Command Set 255
vtex1629_set_euconv_excitation
FUNCTION PROTOTYPE
ViStatus vtex1629_set_euconv_excitation (ViSession vi, ViInt32 _VI_FAR channels[],ViInt32
numberOfChannels, ViReal64 euConversionVoltage);
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 EU conversion excitation
voltage will be set. Valid input values: 0 to 47.
numberOfChannels = the size of the channels list. Valid input values: 1 to 48.
euConversionVoltage = a real input value, in volts, that indicates the value that should be used in EU conversions
for the excitation voltage. Valid input values: 0.00000 to +16.00000.
DATA ITEM RESET VALUE
euConversionVoltage = 0.000000
DESCRIPTION
This function sets the excitation voltage to be used in EU conversions for a particular list of channels.
NOTE The conventional method of providing a non-nominal value of the excitation voltage to the EU
conversion is to conduct an excitation voltage measurement using the
vtex1629_measure_excitation_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};
ViInt32 numberOfChannels = 1;
…
status = vtex1629_set_euconv_excitation(instrumentHandle,
channels,
numberOfChannels,
2.0);
