4. Align the sensor horizontally with the surface to be mea-
sured. The surface temperature is determined using the instal-
led infrared temperature sensor. The greater the distance to
the object, the greater the measuring range. Keep the mea-
surement distance to the object to a minimum. As a rule, the
distance must not exceed 100 cm. If the ascertained surface
temperature is less than the dew point temperature shown on
the display of the HPM touch pro, this means there is conden-
sation on the surface of the object.
5. If required, save the determined ambient values in the
device archive. The process is identical to that for saving moi-
sture measurements.
6. Open the previously determined ambient measurement in
the device archive. Press the button to confirm your
selection.
