15.2.3 Double Maximum Memory with hold time "Combined"

The function of the double maximum memory "combined" is similar to
that of the double maximum memory. However, the hold time starts
when the spectral temperature is at its highest point. Displayed is the
corresponding two-colour temperature. If the spectral temperature de-
creases during the hold time, the corresponding two-colour temperature
is only displayed when the hold time has elapsed. If the spectral temper-
ature rises during the hold time, the corresponding two-colour tempera-
ture is directly displayed.

15.2.4 Automatic Temperature Detection (ATD)

The ATD function allows a very easy and fully automatic capture of the
temperature. As soon as the pyrometer is switched on and aimed at a
hot object, the measurement starts automatically. The threshold value to
detect a hot object is adjustable. Depending on the configuration, the
measurement ends either after a selectable period or when there is no
longer a hot object in the pyrometer's measurement area. At the end of
the measurement the captured value is displayed until a new measuring
object is detected. To eliminate unrealistic measurement differences, it is
possible to check the determined measured value for plausibility in rela-
tion to the previous measured value and to filter it out. The new meas-
ured value can also be averaged with a weighting factor to eliminate
large jumps between the measured values.
