Calibration Programs
B-1
B.1 Introduction
This appendix includes programs written in BASIC and Tur-
bo C to aid you in calibrating the Model 2002. Refer to Sec-
tion 2 for more details on calibration procedures.
B.2 Computer hardware requirements
The following computer hardware is required to run the ex-
ample calibration programs:
• IBM PC, AT, or compatible computer.
• Keithley KPC-488.2, KPS-488.2, or KPC-488.2AT, or
CEC PC-488 IEEE-488 interface for the computer.
• Two shielded IEEE-488 connecting cables (Keithley
Model 7007).
B.3 BASIC program requirements
In order to use the BASIC programs, you will need the fol-
lowing software:
• Microsoft QBasic (supplied with MS-DOS 5.0 or later).
QuickBASIC (version 4.5 or later) or Visual BASIC for
MS-DOS may also be used.
• MS-DOS version 5.0 or later (version 3.3 or later may
be used if not using QBasic).
• HP-style Universal Language Driver, CECHP.EXE
(supplied with Keithley and CEC interface cards listed
above).
B.4 Turbo C program requirements
In order to use the Turbo C programs, you will need the fol-
lowing software:
• MS-DOS or PC-DOS version 3.3 or later.
• Borland Turbo C version 2.0 or later. (Other ANSI-
compatible C compilers can also be used, but some pro-
gram modifications may be necessary.)
• HP-style Universal Language Driver, CECHP.EXE
(supplied with the Keithley and CEC interface cards
listed above).
B.5 Calibration equipment
Table B-1 summarizes recommended comprehensive cali-
bration equipment, and Table B-2 summarizes test equip-
ment required for low-level calibration.
