Reference Pitch and Averaging Time 
Both the Hz Display and the Note Name Display have two additional options at the bottom of the
scope: ref and avg.
ref This displays the reference pitch used by the tuner (which displays the number of Hz to
which the A above middle-C is tuned). Most devices default to 440Hz, but other
standards are sometimes used.
avg This displays how long the Zeroscope spends averaging out frequency variations before
it recalculates and reports a new note name. There are three options: slow; norm; and
fast. Fast is very sensitive to fluctuations on input, while slow is not. Norm is in the
middle.
A small indicator arrow to the left of the ref or avg parameter indicates which will be changed by
rotating the encoder. To change whether the encoder edits ref or avg , switch between Hz and Note
Name displays. Specifically:
1. After entering Tune mode, wait five seconds for the little Tune mode indicator in the upper right
corner to extinguish.
2. With Hz display active, turn the encoder (without pushing it) to change the avg setting (slow,
normal, fast)
3. Switch to the Note Name display, and turn the encoder (without pushing it) to change the ref
tuning value.
