PROBE SENSITIVITY TEST
Sonomed pachymeter probes are constructed to
be reliable products which may be used for
several years. However, the nature of the
transducers within the probes is such that
degradation can occur over extended lengths of
time. The sensitivity test can determine the
sensitivity of a pachymeter probe, and should be
performed if the probe has begun exhibiting
suspect performance.
The P
ACSCAN™ defaults into the Pachymeter
Test Screen every time the Pachymeter mode is
selected. To perform the measurement accuracy
test procedure, follow these steps:
1. Connect the probe connector to the side
panel jack labeled "PROBE". Before
inserting be sure to line up the red indicator
marks on both the jack and cable connector.
2. Make certain that the tip of the probe is
clean and dry and not in contact with any
object.
3. Press [PROBE SENSITIVITY TEST]
button to begin test.
4. The test will commence and display the
sensitivity of the probe on a scale from 0-
100%.
5. If the test results are acceptable (>75%), the
system will indicate the message “PROBE
OK”.
IMPORTANT
A probe which sensitivity test results are not
acceptable (“PROBE WEAK”) may not be
sensitive enough for accurate measurements.
In general this would be due to a loss of
sensitivity in the Probe. If this is the case the
Probe should be replaced. However, in order
to confirm that it is the probe which is the
cause of the problem, it is necessary for
evaluation by Sonomed.

Sonomed Service Department.
