Since the
inverier inpulloutput
voltage and
current include high harmonic components,
meas-
urement r e s u b vary depending on the measuring instrument
and
t h e
circuits used in
meas-
urement. To measure voltage and current
with an
instrument
for
commerclal frequency
application, use the instrument in the table given in the next page and the circuit in the follow-
