niDCPower_InitExtCal

ViStatus niDCPower_InitExtCal (ViRsrc resourceName, ViConstString password, ViSession *newVi);

Purpose

If password is valid, this function creates a new IVI instrument driver session to the device specified in resourceName and returns an instrument handle you use to identify the device in all subsequent NI-DCPower function calls. This function also sends initialization commands to set the device to the state necessary for the operation of NI-DCPower.

Opening a calibration session always performs a reset. Refer to the calibration procedure for the device you are calibrating for detailed instructions on the appropriate use of this function.
