5� Voltage must be applied for at least t > 300 ms� The unit performs a self test�
The display shows
OL
(analogue output 20�5 m)�
To deactivate the diagnostics function, the static signal must be available for a
period of 300 msec „Low“�
If the diagnostics function is activated using the control keys on the instrument, it
will remain in this mode for 10 sec�
13.3 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�

13.4 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 pyrometer,
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�
