HP BASIC / HP-IB Program Example 2

This program example demonstrates how two input channels can be
independently configured and used.
10 !
20 ! This program configures the meter for voltage measurements on two
30 ! input channels. The channels are set to different ranges and
40 ! resolutions to show the independence of the settings for each channel.
