According to the manual, it should be possible to adjust the null to
000, and it should be a broad null. On mine, it was extremely sharp,
and wouldn't get lower than 010, flickering to 011. Does this indicate
a problem? I went ahead and finished the installation -- the voltages
were fine, and the tuner seems to work just dandy.
I'm using a homemade dummy load, which seems to test out ok at least at
the lower frequencies, and I don't have a calibrated wattmeter (yet,
will borrow one soon).
Can/should the null be recalibrated, even though the resister has been
installed?
