Problem Causes and Solutions
Temperature readout is not the
actual temperature of the well With the unit stable, slowly rotate the unit. If no change occurs, the unit
may need to be calibrated. Contact Hart Scientific Customer Service. If the
display changes more than twice the normal display deviation, another unit
in the area could be emitting RF energy. Move the unit to a different loca-
tion and rotate the unit again. If the temperature is correct in this new area
or deviates differently than the first area, RF energy is present in the room.
If you have to perform the test in the effected area, use the comparison test
to eliminate any possible errors.
