Probe Test:
Two numbers will be displayed:
1. The left number determines whether the WATER-sensing
probe is in contact with water.
a. A number of "0" (or close to 0) means that water is in
contact with the probe.
b. A number of "255" (or close to 255) means water is not in
contact with the probe.
2. The right number represents what the TEMPERATURE-
sensing probe reads. The table below is an approximate
correlation between the value and the temperature the probe
is sensing:
a. A number less than "10" indicates that the probe is not
properly connected to the board
b. A number higher than "155" indicate a defective probe.)
