6.0 Trouble Shooting
Why do I get an ERROR after making a probing?
If 50% of the speed readings for a given probing (measured at each 1
cm depth increment) were not within one dot of the center point of the
speedometer then the meter rejects the reading as invalid and show
ERROR on the LCD which requires the user to make the probing
again. With experience the user will get better at producing
consistent penetration speeds that do NOT generate errors. (see
4.3.4)
Why do I get a 0 for mean while the probe average is not 0?
The mean is calculated for up to 6 readings after power on. If the
user takes more than 6 readings the mean and standard deviation will
show as 0’s. Turning the meter OFF then back ON will reset the
counter for up to 6 new readings for which it will calculate mean and
standard deviation. The probe average will always be correct
regardless of the number of readings since power on.
Why don’t I get accurate temperature measurements?
First make sure you are keeping the probe inserted in the product for
4 seconds rather than withdrawing it immediately to end the probing.
If the temperature readings are still not accurate the try withdrawing
the probe 1-2 cm after your full depth is reached. This will help to
insure the temp sensor is in good contact with the product and should
cause it to read better. Note: the probe requires 4 cm of withdrawal
to make it end the probing without waiting for temp stabilization,
therefore it is ok to withdraw 1-2 cm since this won’t break the entry to
temp stabilization mode.
Why does the Speedometer seem “stuck” at the start of the
probing?
The speedometer will automatically show a centered position until the
probe tip reaches a depth of 2 cm. This allows time for the user to
enter the surface of the product and then develop some consistency
to their speed before the speedometer starts showing real values.
Why am I having trouble taking readings near the edge of a
product container?
The meter uses a non-contact infrared sensor which shines an
invisible beam of light out the bottom of the meter front. Make sure its
clear window is clean and that the probe tip is at least 1.5 (3.8 cm)
inches back from the edge of the container so the light beam does not
miss the surface of the product.

7.0 Maintenance
-
Remove the battery from the meter if it will be stored without
use for a long period of time (like 3 months or more)
-
Clean the meter with a soft cloth using soapy water or mild
cleaning agent like Windex®. The meter is sealed against
moisture, dust, and oils but it is not considered water tight and
must NOT be submerged.
-
Check the clear window on the bottom edge of the front of the
meter. This is the window over the Infrared depth sensor and
must be kept clean for best performance. Use only soft cloths
for cleaning this window so it does not get scratched.
-
Note the purpose of the small o-ring around the threaded end of
the shaft is to provide a self-locking feature to the probe tip so
that it does not come loose during use. The o-ring is
compressed when the probe tip is tightened by hand and
should be sufficient to keep the tip from coming loose. The o-
ring is not designed to form a seal nor is it required for
operation.
-
If during normal use an alkaline battery leaks in the meter
please clean the meter immediately and wash hands to remove
any caustic battery electrolyte. The battery electrolyte is water
soluble so please use a wet towel to clean the battery
compartment.
