Programmable DC Electronic Load ________________________________________________________________________________ Introduction: This instrument driver provides programming support for Programmable DC Electronic Load. It contains functions for opening, configuring, taking measurements from, and closing the instrument. ________________________________________________________________________________ Assumptions: To successfully use this module, the following conditions must be met: For GPIB instrument drivers: - the instrument is connected to the GPIB. - the GPIB address supplied to the initialize function must match the GPIB address of the instrument. For VXI instrument drivers: - the instrument is installed in the VXI mainframe and you are using one of the following controller options: Embedded controller MXI MXI2 GPIB-VXI - the logical address supplied to the initialize function must match the logical address of the instrument. For RS-232 instrument drivers: - the instrument is connected to the RS-232 interface. - the COM port, baud rate, parity, and timeout supplied to the initialize function must match the settings of the instrument. ________________________________________________________________________________ Error and Status Information: Each function in this instrument driver returns a status code that either indicates success or describes an error or warning condition. Your program should examine the status code from each call to an instrument driver function to determine if an error occurred. The general meaning of the status code is as follows: Value Meaning ------------------------------- 0 Success Positive Values Warnings Negative Values Errors The description of each instrument driver function lists possible error codes and their meanings ________________________________________________________________________________ How To Use This Document: Use this document as a programming reference manual. It describes each function in the Programmable DC Electronic Load instrument. The functions appear in alphabetical order, with a description of the function and its Visual Basic syntax, a description of each parameter, and a list of possible error codes. ________________________________________________________________________________ Function Tree Layout: Class/Panel Name: Function Name: Initialize Chr6310A_init Init Interface Chr6310A_InitInterface Initialize With Options Chr6310A_Init
