Measured figure is
unstable.
Is lip hook making good contract
with oral mucosa?
Is the file hook dirty?
Make sure the lip hook makes good
contact with the oral mucosa.
Clean the file hook.
Measured figure
overreacts or is
too sensitive.
(Measurements
are too short.
Poor accuracy.
Erratic results.)
Is blood or saliva overflowing
from the opening of the crown?
Is the canal filled with blood,
saliva or chemical solutions?
Is the tooth surface covered
with cutting debris or chemical
solutions?
Is the file touching the gingival
tissue?
If blood or other fluids overflow the
canal, the current will leak to the gums
and the meter will jump to apex.
Clean the canal, canal opening and
tooth crown thoroughly.
The meter bar may suddenly swing
when it breaks the surface of fluids
inside the canal, but it will return to
normal as the file is advanced down
toward the apex.
Clean entire tooth surface.
This will cause the meter bar to
suddenly jump all the way to the “APEX”.
