OVER
The admittance measurement (Peak Ya) has exceeded the scale
maximum (1.5 mmho). Points which are over the limit are plotted at
0 mmho.
BLOCK
The test cannot progress because the measured admittance is less
than 0.2 mmho. This can be caused by:
l probe tip lodged against canal wall
l ear canal occlusion
l collapsed ear canal
l extremely small ear
Repositioning probe tip will usually alleviate this condition.
