I looked over the numbers and the amplifier without drive was about .66 and
when loaded heavy was .75.
I though the fuse would blow when the amp meter was showing enough current
for it to blow with just a capacitor across the line. As we all know a fuse
does not blow at the exect time the current is slightly exceeded.
I had never looked into the effect of inductive and capacitive loads on an
AC line. Just knew there was a power factor due to the lead and lag of
current and voltage. My main item of interist is at Radio Frequency and
only look at the AC power was to make sure it was enough to power the
equipment. I just hapen to see some numbers come up on the meter I had
gotten a few weeks ago and got courious as if it was a cheep meter from
China and giving false readings or if they were reasonable close. I do have
a good multimeter to check the actual voltage and a clamp on meter for the
current. For most work if it is from 5 ot 10 percent from those it is
close enough for me. With the first calculated and displayed values were way
off I started to see why. Such as the meter showed 100 watts and the volt
amp multiplying was showing 150 watts and under load it was 1200 on the
meter and 1500 calculated with the V and I . Checking with a hair dryer for
a mostly resistive load the V and I calculated the same as the meter.
