HP BASIC / HP-IB Program Example 3

This program example demonstrates the use of an SRQ to indicate when
measurements are complete. The meter is set to use external triggering.
Math scaling is also demonstrated.
10 !
20 ! This program configures the meter to make multiple dc voltage measurements
30 ! using an external trigger. The "Operation Complete" bit in the Standard
40 ! Event Register is used to determine when the trigger is received and
50 ! generates an SRQ. This program also shows the use of math scaling.
