14.3 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 [
PhLd
] can be set from 0.1 to 999.9 sec. The maximum
temperature sampled during the defined hold time will be saved. It makes sense
to choose a hold time which is approximately 1.5 times as long as the cycle of
the moving targets. This avoids temperature drops. Rising temperatures are still
recognised at once.
