Crown or metal prosthesis touching gingival tissue
Accurate measurement cannot be obtained if the file touches a
metal prosthesis that is touching gingival tissue. In this case,
widen the opening at the top of the crown so that the file will not
touch the metal prosthesis before taking a measurement.
Cutting debris on tooth
Pulp inside canal
Thoroughly remove all cutting debris on the tooth.
Thoroughly remove all the pulp inside the canal; otherwise an
accurate measurement cannot be made.
Caries touching the gums
In this case, electrical leakage through the caries infected area to
the gums will made it impossible to make an accurate
measurement.
Blocked Canal
The meter will not move if the canal is blocked.
Open the canal all the way to the apical constriction to measure
it.
Extremely dry canal
If the canal is extremely dry, the meter may not move until it is
quite close to the apex. In this case, try moistening the canal
with oxydol or saline.
