*TRG
Triggers the instrument if TRIGger:SOURce BUS is selected.
Parameter Typical Return
(none) (none)
Return five DC voltage measurements, using a software trigger to start the measurements:
CONF:VOLT:DC
SAMP:COUN 5
TRIG:SOUR BUS
INIT
*TRG
FETCH?
Typical Response:+1.00520000E+01, … (5 measurements)
l After setting the trigger source, you must send INITiate to place the DMM in the "wait-for-trigger" state. The *TRG
command will not be accepted unless the DMM is in the "wait-for-trigger" state.
*TST?
Performs a basic self-test of the instrument and returns a pass/fail indication. The TEST:ALL? self-test is more
comprehensive than the *TST? self-test.
Parameter Typical Return
(none) +0 (pass) or +1 (one or more tests failed)
Perform self-test:
*TST?
l The self-test takes just a few seconds to complete.
l If one or more tests fail, the query returns +1 and stores an error in the error queue. For a complete listing of the
error messages related to self-test failures, see Self-test Error Messages.
l Following the test, the instrument returns to the instrument state that existed before the self-test.
*WAI
Configures the instrument's output buffer to wait for all pending operations to complete before executing any
additional commands over the interface.
Parameter Typical Return
(none) (none)
Wait until all pending operations complete:
*WAI
l Configuration changes and measurements are considered pending operations. Therefore, *WAI will cause these
changes to occur and complete.
