the voltage requested (line 13
)
is negative
or
too high, the appropriate error message appears on the display
or three seconds and then the program returns,to line 13.
'roper range is selected and correct data word value (N) is calculated for the voltage re

uifsted.
Data word (N) representing the desired output voltage is sent to the 59501B . Format f4.0 deletes leading
spaces and z suppresses the carriage return/line feed codes (see paragraph 3-34).
