To change the exposure time the corresponding DIP switch for 0.5 s, 1 s, 2 s or 5 s must be set in
the ON position. A longer response time of 10 s can be set if the switch for 0.5 s and 5 s is set to
the ON position at the same time, a longer response time of 30 s can be set if the switch for 1 s
and 5 s is set at to the ON position the same time. In the “OFF” position (Software
InfraWin
:
t
90
= min), the device operates using its time constant (see technical data).
If the settings directly at the pyrometer should be used the pyrometer must be switched into
offline mode (OFFL, see
5.2
). To adjust the exposure time via software, see InfraWin description
in the program’s help menu.
5.1.3
Analog Output 0/4 to 20 mA
When the DIP switch 2 is in the ON position, the analog output will be
4 - 20 mA, in the OFF position, the analog output will be 0 - 20 mA. The
analog output has to be selected according to the signal input of the
connected instrument (controller, PLC, etc.).
If the settings directly at the pyrometer should be used the pyrometer must
be switched into offline mode (OFFL, see
5.2
). To adjust the analog output
via software, see InfraWin description in the program’s help menu.

5.2.1
Maximum / minimum value storage (t
Clear
)
The integrated maximum value storage is activated when the parameter t
clear
is set to something other than “OFF”. If the maximum value storage is
switched on, the highest last temperature value will always be displayed and
stored. The minimum value storage saves the lowest measurement taken
during a reading (e.g. practical when monitoring cooled goods such as frozen
foods). As such, it may be beneficial to periodically clear and reset the stored
values to obtain new temperature readings.
This storage also must be cleared at regular intervals when fluctuating object
temperatures cause the display or the analog outputs to change too rapidly
or when the pyrometer is not constantly viewing an object to be measured.
The maximum value storage value has two different operating modes:
Single Storage:
Single storage mode is used when you want to reset the stored value
using an external impulse via one contact closure from an external relay (such as between
two measured objects). The relay contact is connected directly to the pyrometer between
pins J and K. This mode allows a new value to be established after each impulse from the
reset signal.
Double Storage:
Double storage mode comes into effect when selecting one of the reset
intervals. This mode utilizes two memories. With the first memory, the highest measured
value is held and is deleted alternately in the time interval set (clear time). The other
memory retains the maximum value throughout the next time interval. The disadvantages
of fluctuations in the display with the clock frequency are thereby eliminated.
The following settings are possible:
Off:
When set to OFF, the maximum value storage is switched off and all new temperature
values are measured but not stored.
0.1…25 s:
If any clear time is set, the maximum value is estimated and held in double storage
mode. After the entered time the storage will be deleted.
