Surface Temperature Sensor is connected to the instrument and held against
the surface of interest. Temperature values can be displayed in °C or °F (see
section 2.5 for instructions).
T
DIFF is a useful function when investigating condensation, as it tells the user
how many degrees a surface is above or below the prevailing dew point
temperature. When a surface exceeds the dew point by more than 3°C, T
DIFF is
displayed with the message NO CONDENSATION. When a surface exceeds
the dew point by 3°C or less, T
DIFF is displayed with the message AT RISK, NO
CONDENSATION. When the surface temperature is equal to or lower than the
dew point, a negative T
DIFF is displayed with the message CONDENSATION.
The progress bar is activated when T
DIFF is less than 14°C above the dew
point. The indicator moves from left to right to signify the increasing risk and
degree of condensation. Table 3 below summarizes this functionality.
