Fluke 111 used (which is exactly 1 better than yours Daren, so there
) Warmup ~15 minutes.
A4 keyboard and octave controls used, notes outside this range were tested by adjusting the TUN parameter to +12 and +24
0.008
1.043
2.084
3.125 middle C
4.172
5.211
6.259
7.31
8.36
Side note: I can't get middle C to be exactly 3V without adjusting the "middle C" parameter in the setup menu.
With middle C = +3V I get:
TUN = -2 and FIN = +63 gives 2.974V
TUN = -1 and FIN = -63 gives 3.018V
With middle C parameter set to 2.88V, TUN = 0, FIN = 0 (measured Voltage = 3.001V @ middle C) here are the results:
-0.115
0.921
1.961
3.001 middle C
4.048
5.088
6.135
7.19
8.23
So it looks like I have in the neighborhood of 0.04V/oct tracking error near middle C when calibrated.
