Keithley 2510 User Manual

E-2 Example Programs Models 2510 and 2510-AT User’s Manual
Introduction
This appendix includes two example BASIC programs to demonstrate basic Model 2510
remote operation:
• Program 1: Basic temperature control.
• Program 2: Using setpoint tolerance to generate a temperature sweep.
Program requirements
Computer hardware requirements
The following computer hardware is required to run the example programs:
• IBM PC compatible computer.
• Keithley KPC-488.2, KPS-488.2, or KPC-488.2AT, or CEC PC-488 IEEE-488
interface for the computer.
• Shielded IEEE-488 interface cable (Keithley Model 7007).
Software requirements
In order to use the example programs, you will need the following computer software:
• Microsoft QBasic (supplied with MS-DOS 5.0 or later).
• MS-DOS version 5.0 or later or Windows 95/98.
• HP-style Universal Language Driver, CECHP.EXE (supplied with Keithley and
CEC interface cards listed above).
General program instructions
1. With the power off, connect the Model 2510 to the IEEE-488 interface of the com-
puter. Be sure to use a shielded IEEE-488 cable for bus connections.
2. Turn on the computer and the Model 2510.
3. Make sure the Model 2510 is set for a primary address of 15. (Use the front panel
MENU/COMMUNICATIONS/GPIB selection to check or change the address.)
4. Make sure that the computer bus driver software (CECHP.EXE) is properly initial-
ized.
5. Enter the QBasic editor, and type in the example program from the listing later in
this Appendix.
6. Check thoroughly for errors, then save it using a convenient filename.
7. Run the program, and note any display messages on the computer screen.
