3.4567,2.8405 Waits until the end of the measuring cycle,
copies the values to the interface buffer and
outputs the variables 0 to 1 (Bpk and Hpk).
Both are from the same measuring cycle!!

command header
error:TRM3
You ask the error queue what happened and
get the answer. If you have misspelled more
than this command, you get more answers.

1.2346,00034,0.9984 Waits until the end of the measuring cycle,
copies the values of channel n to the
interface buffer and outputs the amplitudes of
the current harmonics of order 3 to 5. All are
from the same measuring cycle!!

Defines that the voltage and the power
should be output after every measuring cycle,
without any further request.

Activates this continuous output of the values
defined with ‘actn’. (until the CONT OFF
command!)

56, -3204, +4506 calculates new information to the sampled
values of group B (0 = group A, 1 = group
B), reads which values are stored and how
much values are stored before and after the
trigger

deactivates the scope memory
10 gtl Changes from the remote to the local state.
So the instrument can be controlled manually
10.2.20 SHORT command Example
This shows you as an example (in SHORT language), what you could send, what the
instrument should answer and some comments about this. Some of the responses like
measuring values depend on measured signals, so they may be different, if you try this
examples. This examples work with a new powered on instrument (no commands before!). For
testing some functions we recommend to use the RS232 interface, because it is much more
simple to use than the IEEE interface. In principal the example works with both interfaces.
