Common Commands 9-5
*RST — reset Return power supply to RST defaults
When the *RST command is sent, the power supply performs the following operations:
1. Returns the instrument to the RST default conditions (see “Default” column of SCPI
tables).
2. Cancels all pending commands.
3. Cancels response to any previously received *OPC and *OPC? commands.
*TRG[1] — trigger Send battery channel (#1) bus trigger to
power supply
*TRG2 — trigger Send charger channel (#2) bus trigger to
power supply
Use the *TRG command to trigger a single reading for the function presently selected. If the
a
verage count is >1, then the single reading will be the average reading.
*TST? — self-test query Run self test and read result
Use this query command to perform a checksum test on ROM. The command places the
code
d result (0 or 1) in the output queue. When the power supply is addressed to talk, the coded
result is sent from the output queue to the computer.
A returned value of zero (0) indicates that the test passed, and a value of one (1) indicates that
the test f
ailed.
*WAI — wait-to-continue Wait until previous commands are com-
pleted
Effectively, the *WAI command is a no-op (no ope
ration) for the power supply and therefore,
does not need to be used.
Two types of device commands exist:
• Sequential commands — A command whose operations are allowed to finish before the
ne
xt command is executed.
• Overlapped commands — A command that allows the execution of subsequent
commands while de
vice operations of the overlapped command are still in progress.
The *WAI command is used to suspend the execution of subsequent commands until the
de
vice operations of all previous overlapped commands are finished. The *WAI command is not
needed for sequential commands.
