Sub Main()

Dim dmm As New Agilent34401

dmm.Initialize("GPIB::23", False, True, "simulate=true")

dmm.Function = Agilent34401FunctionEnum.Agilent34401FunctionDCVolts

dmm.DCVoltage.Configure(1.5, 0.001) dmm.Trigger.Delay = 0.01

Dim reading As New Double

reading = dmm.Measurement.Read(1000) dmm.Close()

Console.WriteLine(“The reading is {0}”, reading) Console.ReadLine()

•To use Visual Basic, select Visual Basic in Project Types.

•To enforce type checking, insert a line at the start of the code. Type

Option Explicit On

•To call the DCVolts function you need to insert a line of code. Type
