lator) for controlling the unipolar output of the 59501B is
given in example 6. The program includes a calibration
routine and allows the operator to input specific voltage
values on the keyboard. The program also provides auto¬
matic range changing and error messages that indicate if the
voltage value requested exceeds 9.99V or if a negative voltage
is requested. A line-by-line explanation is given after the
program. Programming fundamentals are provided in
paragraphs 3-29 through 3-34.

the 9825A's internal strip printer. Also, a check
sum is provided at the end of each 9825A program
listing. Make sure that the check sum at the end
of your keyed-in program matches the check sum
provided in the listing.
