If the diagnostics function is activated using the control keys on the instrument, it
will remain in this mode for 10 sec�
If the diagnostics function is not used, connect the diagnostics input (Pin
5) to minus� As an alternative, use a 4-pole cable box where Pin 5 is not
assigned�
11.4 Damping function
When the target object's temperature is erratic, the damping function smoothens
these temperature fluctuations in order to stabilize the measuring signal. The
greater the time constant [DAP], the lower the effect of these fluctuations on the
yielded temperature reading�

2: Output signal with smoothing function
11.5 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 infrared
temperature sensor, resulting in temperature readings which would appear to be
cyclical� In this mode, the displayed temperature reading will not drop between tar-
geted objects� The peak temperature reading will be held for a preset time period�
The hold time [PhLd] can be set at 100, 300 and 500 msec� 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 mov-
ing targets� This avoids temperature drops� Any changes are recognised at once�
