11.11 Peak hold function
It might often be desirable to determine the peak temperature during a defined
time period, for example when the objects to be measured move past the pyrom-
eter, resulting in temperature readings which would appear to be cyclical� In this
mode, the displayed temperature reading will not drop between targeted objects�
The peak temperature reading will be held for a preset time period�
The hold time [S] → [S . P hd] → [t iME] can be set from 0.1 to 999.9 sec.
The maximum temperatures sampled during the defined hold time will be saved� It
make sense to choose a hold time which is approximate 1�5 time as long as cycle
of the moving targets� This avoids temperature drops� Any changes are recognised
at once�

11.12 ATD function
This function is used to automatically measure the temperature of a discontinuous-
ly running process� For example, it can be used to determine the temperature of
bolts passing the pyrometer acyclically and which have a variable length�
