Fluke 5500A - Overlapped Commands; Sequential Commands; Commands that Require the Calibration Switch to be Enabled; Commands for RS-232 Only

Remote Operation
Using Commands 5
5-29
5-31. Overlapped Commands
Commands that begin execution but require slightly more time to complete are called
overlapped commands, because they can be overlapped by the next command before
they have completed execution.
In Chapter 6, the command graphic shows a check mark for
Overlapped
x
commands.
The 25 overlapped commands are:
BOOST RANGELCK
CUR_POST *RST
DC_OFFSET RTD_TYPE
DPF SCOPE
DUTY SRC_PREF
EARTH STBY
HARMONIC TC_OFFSET
INCR TC_OTCD
LOWS TC_REF
MULT TC_TYPE
OPER TRIG
OUT TSENS_TYPE
OUT_IMP WAVE
PHASE ZCOMP
You can use the command *WAI to wait until the overlapped command has completed
execution before executing the next command. For example,
OUT 1 V, 1 A, 60 HZ ; *WAI
You can also use the status commands *OPC and *OPC? to detect completion of
overlapped commands. (See “Checking 5500A Status.”)
5-32. Sequential Commands
Commands that execute immediately are called sequential commands.
In Chapter 6, the command graphic shows a check mark for
Sequential
x
commands.
The majority of the commands, 87 of 111 commands, are sequential.
5-33. Commands that Require the Calibration Switch to be Enabled
The following commands do not work unless the rear panel CALIBRATION switch is in
the ENABLE position:
FORMAT ALL
FORMAT CAL
*PUD
Attempting to use any of these commands with the CALIBRATION switch in the
NORMAL position logs an error into the error queue. (Or it returns the error message if
in the RS-232 Terminal Mode.)
5-34. Commands for RS-232 Only
Commands that are used for the RS-232 interface only are identified in the command
graphic by checking the
IEEE-488 RS-232
x
check box.
