Description
This program measures (DCV) the two high speed channels
(ch 5 and 10) of the Model 2001-SCAN Scanner Card. Each
channel is measured five times for a total of 10 measurements. The DCV reading and the elapsed time for each measurement are displayed on the computer CRT.
Required equipment
• Model 2002 Multimeter
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.
