:CLEar
:SYSTem:CLEar Clear Error Queue
This action command is used to clear the Error Queue of messages.
PRINT #1, "output 16; :syst:cle" ' Clear Error Queue
:LFRequency
:SYSTem:LFRequency Query power line frequency
This query command is used to read the frequency of the power line that powers the Model
2002.
PRINT #1, "output 16; :syst:lfr?" ' Query the power line
PRINT #1, "enter 16" ' Get response from 2002
:DATE <yr>, <mo>, <day>
:SYSTem:DATE <yr>, <mo>, <day> Set date for clock
<yr> = 1993 to 2092 Specify year
<mo> = 1 to 12 Specify month
<day>= 1 to 31 Specify day
:DATE? Query the date
This command is used to set the date for the real-time clock. Setting an invalid date (i.e. Febru-
ary 29, 1994) result in an error and the previous date is retained.
PRINT #1, "output 16; :syst:date <1993>, <12>, <1>; date?" ' Set date to
December 1, 1993
and query
PRINT #1, "enter 16" ' Get response
message from
2002
:TIME <hr>, <min>, <sec>
:SYSTem:TIME <hr>, <min>, <sec> Set time for clock
<hr> = 0 to 23 Specify hour (24 hr format)
<min> = 0 to 59 Specify minute
<sec>= 0.00 to 59.99 Specify second (rounded to 1/100 sec.)
:TIME? Query the time
This command is used to set the time for the real-time clock. Note that the time must be set using
the 24-hour format (i.e. hour 13 is 1PM). Setting an invalid time results in an error and the pre-
vious time is retained.
:TIME? returns the time to nearest hundreth of a second.
PRINT #1, "output 16; :syst:time <14>, <36>, <0>; time?" ' Set time to 2:36
pm and query
PRINT #1, "enter 16" ' Get response mes-
sage from 2002
