Why does my heat mat surface measure a different temperature with a temperature gun than is shown on the IMC?
Because
the temperature sensor is built into the heat mat, the temperature it measures
may be different than the actual mat surface temperature. Use the Sensor
Correction setting to adjust the IMC reading to match the temperature gun
reading. The default setting adjusts the reading to work with Hog Hearth® heat
mats. For more information see Parameter 5, sensor correction in the
user manual.
