HP 59501A Operating Manual page 14

To set the output current of a 10 A supply to 0.661 A
1. Compute .661/10 - 6.61%
2. Program
OUTPUT 706 USING ''#,4D";1661
Low Level DC Signal Source:
To output 6.72 V, program
OUTPUT 706 USING ''#,4D":2672
Programming with variables allows the output value
to be updated or changed with relative ease. The
following programming examples may be entered into
your HP 8.5 and run to demonstrate this type of pro¬
gramming. These programs ask for power supply out¬
put voltage, then scale that value up (or down) and
calculate the correct 59501A programming word,
NOTE: The 59501A should be calibrated first,
to
obtain
accurate output levels and avoid possible damage to
the programmed power supply.
