Does the button work?

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?
Is there pulp tissue left inside
the root canal?
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”.
Accurate measurements cannot be
obtained if a large amount of pulp
tissue is left inside the root canal.
