ProCheck
6. Troubleshooting
29
SOLUTION
: The ProCheck is reading a value below (or
above) the expected value for the sensor. This could indi-
cate a broken sensor. Check to make sure the sensor is fully
plugged in and the correct sensor type is chosen in the sen-
sor menu.
PROBLEM
: My ProCheck says “Invalid Response” or “No
Response” on the display.
SOLUTION
: The ProCheck is unable to communicate
with a digital sensor. Check to make sure the sensor is fully
plugged in and the correct sensor type is chosen in the sen-
sor menu. Try pressing the
ENTER
button several times
to restart the sensor measurement. If these steps fail, the
sensor is probably broken.
PROBLEM
: The data shown for my ProCheck doesn’t
seem correct.
SOLUTION
: If you are using a custom calibration, be sure
that the coefficients are properly entered in the sensor con-
figure menu. Check to make sure the sensor type shown
in the sensor menu on the main screen matches the sensor
type plugged into the ProCheck. If these steps don’t resolve
the problem, please consult the sensor’s user manual for
more information.
