Description
Every time this program is run, the Model 2002 goes to the
most sensitive DCV range and makes a single measurement
using the :MEASure command. The reading is then dis-
played on the computer CRT.
Required equipment
• Model 2002 Multimeter
• Microsoft QuickBASIC 4.5
• Any one of the following IEEE-488 interfaces:
Keithley Model KPC-488.2
Keithley Model KPC-488.2AT
Capital Equipment Corporation PC<>488
The program assumes that the Model 2002 is set to address
16.
Loading user library
The user library for QuickBASIC 4.5 is provided with the
IEEE-488 interface (ieeeqb.qlb). Assuming QuickBASIC
and the user library are in the same DOS directory, enter the
following command line from the DOS prompt:
QB /L ieeeqb.qlb
The above command line will load QuickBASIC and the
user library.
