Why does my heat mat surface temperature measure a different temperature with a temperature gun than is shown on the HMB?

Why does my heat mat surface temperature measure a different temperature with a temperature gun than is shown on the HMB?

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 HMB reading to match the temperature gun reading. The default setting adjusts the reading to work with Hog Hearth® heat mats. For more information see Setting the sensor correction value in the user manual.
