Yes, thanks Verner. I found that page too. But the .7 to 1% spec is
inadequate. I'm hoping I can find someone with the actual
documentation that comes with the unit. I'm certain that the unit is
not accurate to 1% when measuring 4 pf. 1% would be .04 pf and I
suspect the unit is actually accurate to about 1% near full scale not
near the bottom of the scale. I would expect to find a spec that is
something like 1% plus one digit plus .5 pf - or something along those
lines. The Boonton $4500 testers are accurate to .5% plus a digit plus
.5 pf and suspect my $200 instrument is not in that same class.
So, does anyone know or have the detailed accuracy spec on the lowest
range?
Thanks,
Michael
