C / 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.
/***************************************************************************
This program configures the meter to make multiple dc voltage
measurements using an external trigger. The "Operation Complete" bit
in the Standard Event Register is used to determine when the trigger
is received and generates an SRQ. This program also shows the use of
math scaling.
