User manual

All examples presume QuickBASIC version 4.5 or higher and a CEC IEEE-488 interface
card with CEC driver version 2.11 or higher, with the Model 2000 at address 16 on the IEEE-
488 bus.
The Model 2000 has independent controls for each of its measurement functions. This
means, for example, that autorange can be turned on for DC voltage while leaving it off for
AC voltage.
Another difference is in the parameter to the range command. In other instruments, a sin-
gle number was used to denote each range. The parameter of the SCPI RANGe command is
given as "the maximum value to measure." The instrument interprets this parameter and
goes to the appropriate range. When you query the range with RANGe? the instrument sends
back the full-scale value of its present range.
The following example program illustrates changing function and range. It sets the range
for several functions, then takes readings on each of those functions.
Note that the Model 2000 rounds the range parameter to an integer before choosing the
appropriate range. Sending VOLTage:DC:RANGe 20.45 will set the Model 2000 to the
100V range.
