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.
