HP Drive manual Variantfalse Varianttrue, Hr = driver-getDCVoltage&pDMMDCVolt

5In the doOpen() interface function, insert the following code below the line Please insert your CEM driver code here:

hr = driver.CoCreateInstance(CLSID_Agilent34401); if (FAILED(hr))

{

Display("\033[30;41m Bad return from

CoCreateInstance() method\033[m\n");

}

hr = driver->Initialize(CComBSTR("GPIB0::23::INSTR"),

VARIANT_FALSE,

VARIANT_TRUE,

CComBSTR("Simulate=TRUE"));

if (FAILED(hr))

{

Display("\033[30;41m Bad return from Initialize() method\033[m\n");

}

Note: doOpen is called for the first time when the run-time system loads the PAWS project. If you intend to use non-ATLAS modules in your ATLAS code, subsequent calls to doOpen will be made and you will need to execute the code above only once.

6To set the function for DC Voltage, the range to 1.5 volts, and the resolution to 1 millivolt, select the DMM.cpp file from the PAWS Project window.

7In the DMM_Setup() interface function, insert the following code below the line Please insert your CEM driver code here :

hr = driver->put_Function(Agilent34401FunctionDCVolts); if (FAILED(hr))

{

Display("\033[30;41m Bad return from

put_Function(Agilent34401FunctionDCVolts)method\033[m\n" );

}

hr = driver->get_DCVoltage(&pDMMDCVolt);
